History Of Google By Google

Our company has packed a lot in to a relatively young life.
We‘ve captured some of the key milestones in Google‘s development.

1995-1997 · 1998 · 1999 · 2000 · 2001 · 2002 · 2003 · 2004 · 2005 · 2006 · 2007 · 2008 · 2009 · 2010


1995

* Larry Page and Sergey Brin meet at Stanford. (Larry, 22, a U Michigan grad, is considering the school; Sergey, 21, is assigned to show him around.) According to some accounts, they disagree about most everything during this first meeting.

1996

* Larry and Sergey, now Stanford computer science grad students, begin collaborating on a search engine called BackRub.
* BackRub operates on Stanford servers for more than a year—eventually taking up too much bandwidth to suit the university.

1997

* Larry and Sergey decide that the BackRub search engine needs a new name. After some brainstorming, they go with Google—a play on the word “googol,” a mathematical term for the number represented by the numeral 1 followed by 100 zeros. The use of the term reflects their mission to organize a seemingly infinite amount of information on the web.

1998

August

* Sun co-founder Andy Bechtolsheim writes a check for $100,000 to an entity that doesn‘t exist yet: a company called Google Inc.

September

* Google sets up workspace in Susan Wojcicki‘s garage at 232 Santa Margarita, Menlo Park.
* Google files for incorporation in California on September 4. Shortly thereafter, Larry and Sergey open a bank account in the newly-established company‘s name and deposit Andy Bechtolsheim‘s check.

This is Wikipedia

Like it or loathe it, Wikipedia is a force. When contributors penned its new entry on Norwegian actress Beate Eriksen on Aug. 17, the English-language version of the controversial user-generated encyclopedia reached 3 million entries. More impressive still: more than 10 million users contributed to that milestone. Not bad for a service originally conceived as an afterthought to Nupedia, a failed first attempt by Internet entrepreneur Jimmy Wales and philosopher Lawrence Sanger at creating a free online encyclopedia.

When Nupedia was created in 2000, the plan was for it to feature expert-written, peer-reviewed content. But it suffered from a major problem: a lack of speed. In its first six months, only two articles made it through the process. To spur better production, Sanger suggested creating a counterpart that anyone could contribute to without editorial review. Wikipedia.com went live on Jan. 15, 2001, and the new model quickly eclipsed its older sibling. By the end of the first year, Wikipedia contained more than 20,000 articles in 18 languages. Since then, the site has grown rapidly, swelling to 250,000 articles by 2004 and a million by 2006.
Even in its earliest days, Wikipedia had to reckon with a slew of problems. Among them were vandalism and the lack of a fixed formula for determining what should and shouldn't be included in an encyclopedia unconstrained by physical limitations. The emerging community included a volunteer army of editors, who helped to keep the content aligned with Wikipedia's rules, the first version of which Sanger created in 2002. As the project grew, vandalization and dilution of the encyclopedia's content became more difficult to address. The site's software keeps a log of every modification to every page, and this tracking system has been used to bust some high-profile offenders. In May, Wikipedia banned IP addresses owned by the Church of Scientology on the grounds that Scientologists were making edits that didn't suggest a "neutral point of view" — the encyclopedia's golden rule.

But since its inception, the biggest issue dogging Wikipedia has been concerns about its accuracy. Sanger himself left Wikipedia in 2002 over questions about the legitimacy of the project's entries; he later established a competing encyclopedia, Citizendium, with more rigorous contribution criteria. While a 2005 study by Nature found that Wikipedia's science entries came close to matching the Encyclopaedia Britannica's in terms of accuracy — with 2.92 mistakes per article for Britannica and 3.86 for Wikipedia — no one argues that Wikipedia's content is flawless. Critics say the writing is clunky or prone to bias and that the authors focus on pet projects. Indeed, the site's list of Star Wars creatures totals more than 15,000 words, while the entire entry on World War II has just 10,000.

Running an organization as influential as Wikipedia isn't inexpensive. The company's costs reach nearly $6 million per year, and though it recorded more than 100 billion page views last year, the site has no advertisements. With that level of traffic, even a single text advertisement per page would net Wikipedia millions of dollars, but Wales is insistent that the service, which is supported by private donations, remains ad-free.

As impressive a milestone as 3 million articles is, it simply makes the English Wikipedia the largest component of a massive international enterprise. Wikipedia now contains more than 13 million articles in 271 different languages. The German-language version is the next largest, with more than 900,000 entries, but there's something for readers of every language. Even Cheyenne, which is spoken by only 1,700 Native Americans, has its own version of Wikipedia, although it boasts just 62 articles. Wales, who remains the "spiritual head" of the movement, says he wants Wikipedia to one day contain the sum of human knowledge. It has a way to go, but in just a few years the site has come closer to reaching that lofty goal than anything else.

* 2005: Believe it or not, just this year two people created the most successful video site Internet: Youtube, which since its inception was unstoppable and even Google was able to compete with him and evicted its video portal. Currently as you probably know Youtube is owned by Google who realized that the only way to win the battle of the portals was buying YouTube videos

* 2009: This is the year when Google starts to scary: After a long time stands a real rival for their most successful product (the browser.) Bing introduces the innovative technology Powerset semantic search but despite this and spend millions of dollars in advertising, do not get the acceptance I expected, since even today the market continues to struggle to steal the powerful google search engine.
* 2010: This year is really important for Hotmail since it incorporates many of features that seek to make a more social site with Hotmail. If you could go back in time and see the improvements probably would stay impacted Hotmail. What we now assume as natural a product of years of constant development. Hotmail now has updated most of the accounts of its users and gradually get used to the new design and functions...
* 2011: A challenging year.Lets hope for extraordinary success.

As you can see a lot of things has happened since Hotmail was launched in 1997, and could not be otherwise because they are more than 14 years of history, and – no doubt – you can tell by this and other things, we’ve been in the past…

The History Of Yahoo

The History of Yahoo! - How It All Started...

Yahoo! began as a student hobby and evolved into a global brand that has changed the way people communicate with each other, find and access information and purchase things. The two founders of Yahoo!, David Filo and Jerry Yang, Ph.D. candidates in Electrical Engineering at Stanford University, started their guide in a campus trailer in February 1994 as a way to keep track of their personal interests on the Internet. Before long they were spending more time on their home-brewed lists of favorite links than on their doctoral dissertations. Eventually, Jerry and David's lists became too long and unwieldy, and they broke them out into categories. When the categories became too full, they developed subcategories ... and the core concept behind Yahoo! was born.

The Web site started out as "Jerry and David's Guide to the World Wide Web" but eventually received a new moniker with the help of a dictionary. The name Yahoo! is an acronym for "Yet Another Hierarchical Officious Oracle," but Filo and Yang insist they selected the name because they liked the general definition of a yahoo: "rude, unsophisticated, uncouth." Yahoo! itself first resided on Yang's student workstation, "Akebono," while the software was lodged on Filo's computer, "Konishiki" - both named after legendary sumo wrestlers.

Jerry and David soon found they were not alone in wanting a single place to find useful Web sites. Before long, hundreds of people were accessing their guide from well beyond the Stanford trailer. Word spread from friends to what quickly became a significant, loyal audience throughout the closely-knit Internet community. Yahoo! celebrated its first million-hit day in the fall of 1994, translating to almost 100 thousand unique visitors.

Due to the torrent of traffic and enthusiastic reception Yahoo! was receiving, the founders knew they had a potential business on their hands. In March 1995, the pair incorporated the business and met with dozens of Silicon Valley venture capitalists. They eventually came across Sequoia Capital, the well-regarded firm whose most successful investments included Apple Computer, Atari, Oracle and Cisco Systems. They agreed to fund Yahoo! in April 1995 with an initial investment of nearly $2 million.

Realizing their new company had the potential to grow quickly, Jerry and David began to shop for a management team. They hired Tim Koogle, a veteran of Motorola and an alumnus of the Stanford engineering department, as chief executive officer and Jeffrey Mallett, founder of Novell's WordPerfect consumer division, as chief operating officer. They secured a second round of funding in Fall 1995 from investors Reuters Ltd. and Softbank. Yahoo! launched a highly-successful IPO in April 1996 with a total of 49 employees.

Today, Yahoo! Inc. is a leading global Internet communications, commerce and media company that offers a comprehensive branded network of services to more than 345 million individuals each month worldwide. As the first online navigational guide to the Web, www.yahoo.com is the leading guide in terms of traffic, advertising, household and business user reach. Yahoo! is the No. 1 Internet brand globally and reaches the largest audience worldwide. The company also provides online business and enterprise services designed to enhance the productivity and Web presence of Yahoo!'s clients. These services include Corporate Yahoo!, a popular customized enterprise portal solution; audio and video streaming; store hosting and management; and Web site tools and services. The company's global Web network includes 25 World properties. Headquartered in Sunnyvale, Calif., Yahoo! has offices in Europe, Asia, Latin America, Australia, Canada and the United States.

SIM (Subscribers Identity Module)

A subscriber identity module or subscriber identification module (SIM) on a removable SIM card securely stores the service-subscriber key (IMSI) used to identify a subscriber on mobile telephony devices (such as mobile phones and computers). The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device.

A SIM card contains its unique serial number, internationally unique number of the mobile user (IMSI), security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to and two passwords (PIN for usual use and PUK for unlocking).

SIM cards are available in three standard sizes. The first is the size of a credit card (85.60 mm × 53.98 mm x 0.76 mm). The newer, most popular miniature version has the same thickness, but has a length of 25 mm and a width of 15 mm, and has one of its corners truncated (chamfered) to prevent misinsertion. The newest incarnation known as the 3FF or micro-SIM has dimensions of 15 mm × 12 mm. Most cards of the two smaller sizes are supplied as a full-sized card with the smaller card held in place by a few plastic links; it can easily be broken off to be used in a device that uses the smaller SIM.

The first SIM card was made in 1991 by Munich smart card maker Giesecke & Devrient, who sold the first 300 SIM cards to Finnish wireless network operator Radiolinja.

Smart card technology
There are three operating voltages for SIM cards: 5 V, 3 V and 1.8 V (ISO/IEC 7816-3 classes A, B and C respectively). The operating voltage of the majority of SIM cards launched before 1998 was 5 V. SIM cards produced subsequently are compatible with 3 V and 5 V or with 1.8 V and 3 V.

A W-SIM is a SIM card that incorporates core cellular technology in the card itself.

A virtual SIM is a mobile phone number provided by a mobile network operator that does not require a SIM card to terminate phone calls on a user's mobile phone.

Features added in later releases
The specification that standardized the micro-SIM form factor continues to evolve. Some features introduced recently include:

* a micro-SIM form factor
* allow for multiple simultaneous applications accessing the card through logical channels;
* introduce mutual authentication as a way to eliminate carrier spoofing by allowing the SIM card to authenticate the cell tower to which it is connecting;
* add a new PIN protection with hierarchical PIN management with a universal PIN, an application PIN and a local PIN; and
* expand the phonebook storage of the SIM card with entries for email, second name, and groups.

Card sizes
SIM cards were first made the same size as a credit card (85.60 mm × 53.98 mm × 0.76 mm). The development of physically smaller mobile devices prompted the development of a smaller SIM card, the mini-SIM card. Mini-SIM cards have the same thickness as full-size cards, but their length and width are reduced to 25 mm × 15 mm.

The mini-SIM card has the same contact arrangement as the full-size SIM card and they are normally supplied within a full-size card carrier, attached by a number of linking pieces. This arrangement (defined in ISO/IEC 7810 as ID-1/000) allows for such a card to be used in a device requiring a full-size card, or to be used in a device requiring a mini-SIM card after cleanly breaking the scorings manufactured in the outline of a mini-SIM card.

Even smaller device sizes have prompted the development of a yet smaller card size, the 3FF card or micro-SIM. Micro-SIM cards have the same thickness and contact arrangement again, but the length and width are further reduced to 15 mm × 12 mm. The specifications for the 3FF card or micro-SIM also include additional functionality beyond changing the physical card size.


Development of the micro-SIM
The micro-SIM was developed by the European Telecommunications Standards Institute along with SCP, 3GPP (UTRAN/GERAN), 3GPP2 (CDMA2000), ARIB, GSMAssociaton (GSMA SCaG and GSMNA), GlobalPlatform, Liberty Alliance, and the Open Mobile Alliance (OMA) for the purpose of fitting into devices otherwise too small for a mini-SIM card.[2][3]

The form factor was mentioned in the Dec 1998 3GPP SMG9 UMTS Working Party, which is the standards-setting body for GSM SIM cards,[4] and the form factor was agreed upon in late 2003.[5]

The micro-SIM was created with backwards compatibility in mind. The major issue with backwards compatibility was the contact area of the chip. Retaining the same contact area allows the micro-SIM to be compatible with the previous, larger SIM readers through the use of plastic cutout surrounds. The SIM was also designed to run at the same speed (5 MHz) as the previous version. The same size and positions of pins resulted in numerous "How-to" tutorials and YouTube video with detailed instructions how to cut a mini-SIM card to micro-SIM size with sharp knife or scissors. These tutorials became very popular among first owners of iPad 3G after its release on April 30, 2010 and iPhone 4 on June 24, 2010.

The chairman of EP SCP, Dr. Klaus Vedder, said
"With this decision, we can see that ETSI has responded to a market need from ETSI customers, but additionally there is a strong desire not to invalidate, overnight, the existing interface, nor reduce the performance of the cards. EP SCP expect to finalise the technical realisation for the third form factor at the next SCP plenary meeting, scheduled for February 2004."

Usage in mobile phone standards
The use of SIM cards is mandatory in GSM devices. The equivalent of a SIM in UMTS is called the Universal Integrated Circuit Card (UICC), which runs a USIM application, while the Removable User Identity Module (R-UIM) is more popular in CDMA-based devices e.g. CDMA2000. The UICC is still colloquially called a SIM card. Many CDMA-based standards do not include any removable card, and the service is bound to a unique identifier contained in the handset itself.

The satellite phone networks Iridium, Thuraya and Inmarsat's BGAN also use SIM cards. Sometimes these SIM cards work in regular GSM phones and also allow GSM customers to roam in satellite networks by using their own SIM card in a satellite phone.

The SIM card introduced a new and significant business opportunity of mobile telecoms operator/carrier business of the mobile virtual network operator (MVNO) which does not own or operate a cellular telecoms network, but which leases capacity from one of the network operators, and only provides a SIM card to its customers. MVNOs first appeared in Denmark, Hong Kong, Finland and the UK and today exist in over 50 countries including most of Europe, USA, Canada, Australia and parts of Asia and account for approximately 10% of all mobile phone subscribers around the world.
On some networks, the mobile phone is locked to its carrier SIM card, meaning that only the specific carrier's SIM cards will work. This is more common in markets where mobile phones are heavily subsidised by the carriers, and the business model depends on the the customer staying with the service provider for a minimum term (typically, 12 or 24 months). Common examples are the GSM networks in the USA, Canada, the UK and Poland.

A plethora of online and high-street (third-party) businesses now offer the ability to remove the SIM-lock from a phone, effectively making it possible to then use the phone on any network by inserting a different SIM card. Some of these resellers use wholeseller databases.[7] This is a useful benefit for travellers that might want to put a local SIM card into their phone when they arrive in a country, in order to minimize roaming charges. In many countries, now it is possible to buy a pre-pay SIM card just by walking into a store, and these SIM-only deals are a cost effective way to stay in contact when travelling.

Phones sold as pre-pay often come with an operator subsidy, especially in competitive mobile markets like the UK. These phones are sold not just through mobile phone stores, but also supermarkets, catalogs, stationery outlets and online; thus the mobile companies are constantly competing to lower the price. Prepay phones come with a bundled SIM, which can be activated by the user in case the phone is bought up. The handsets are often SIM-locked to ensure that the user does not use another operator, allowing the original operator to eventually recoup its subsidy. However, because the units can be unlocked for a small fee (and even the operators themselves offer this service), units can be bought cheaply, separated from the original SIM card and sold on for a profit, perhaps in other markets, perhaps as contract phone. This is known in the industry as box breaking, and often harms the profits of the operator while allowing complicit sales staff and box breakers to reap the rewards. Note that, if a prepaid handset breaks, the SIM card (representing the prepaid account value, plus user's address book, history, etc) can typically be moved to another prepaid handset if the phone-network is the same. That is, the account is tied to the portable SIM card, not the handset, on prepaid phones. This is useful because by 2010, prepaid handsets cost less than the value a user might have stored in an account.

Mostly, GSM and 3G mobile handsets can easily be SIM-unlocked and used on any suitable network with any SIM card. A notable exception is the Apple iPhone, where in most markets Apple has gone to extreme lengths to lock-down their phones; thus they can only be used with the partner's network. This has led to a popular hack called the jailbreak, which allows custom software unapproved by Apple to run on the phone. Then software can be run to unlock the phone, which frees the iPhone from the partner network; thus any SIM card can be inserted. (Note that jailbreaking, in itself, does not unlock the phone, and has other uses as well.) Apple and the hackers are locked in a war of escalation - described by Apple CEO Steve Jobs as "a game of cat and mouse"[8] - with Apple constantly trying to close loopholes in their operating system, and the hackers finding new ways to jailbreak each version when it becomes available.

In countries where the phones are not subsidised e.g. Italy and Belgium, all phones are unlocked. Where the phone is not locked to its SIM card, the users can easily switch networks by simply replacing the SIM card of one network with that of another while using only one phone. This is typical, for example, among users who may want to optimise their telecoms traffic by different tariffs to different friends on different networks.

Dual SIM phones are now made by some mobile phone manufacturers, which save the user from carrying around a separate phone for every number. There are two types, the first, that allow one to switch between the SIMs, and the second, that allow both SIMs to be active simultaneously.

Mobile Phones


A mobile telephone or cellular telephone (commonly, "mobile phone" or "cell phone") is a long-range, portable electronic device used for mobile communiction. In addition to the standard voice function of a telephone, current mobile phones can support many additional services such as SMS for text mesasaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception are satellite phones).

History

The introduction of hexagonal cells for mobile phone base stations, invented in 1947 by Bell Labs engineers at AT&T, was further developed by Bell Labs during the 1960s. Radiophones have a long and varied history going back to the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held cellular radio devices have been available since 1983. Due to their low establishment costs and rapid deployment, mobile phone networks have since spread rapidly throughout the world, outstripping the growth of fixed telephony.
In 1945, the 0G generation of mobile telephones were introduced. 0G mobile telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since they did not support the automatic change of channel frequency in the middle of a call, when the user moved from one cell (base station coverage area) to another cell, a feature called "handover".

In 1970 Amos Joel of Bell Labs invented the "call handoff" feature, which allowed a mobile-phone user to travel through several cells during the same conversation. Martin Cooper of Motorola is widely considered to be the inventor of the first practical mobile phone for handheld use in a non-vehicle setting. Using a modern, if somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on April 3, 1973. At the time he made his call, Cooper was working as Motorola's General Manager of its Communications Division.

Fully automatic cellular networks were first introduced in the early to mid-1980s (the 1G generation). The first fully automatic mobile phone system was the 1981 Nordic Mobile Telephone (NMT) system. Until the early 1990s, most mobile phones were too large to be carried in a jacket pocket, so they were usually permanently installed in vehicles as car phones. With the advance of miniaturization and smaller digital components, mobile phones got smaller and lighter.


Manufacturers

Nokia Corporation is currently the world's largest manufacturer of mobile telephones, with a global market share of approximately 36% in Q1 of 2007.Other mobile phone manufacturers include Audiovox (now UT Starcom), Benefon, BenQ-Siemens, High Tech Computer Corporation (HTC), Fujitsu, Kyocera, 3G, LG Mobile, Motorola, NEC, Panasonic (Matsushita Electric), Pantech Curitel, Philips, Research In Motion, Sagem, Samsung, Sanyo, Sharp, Siemens, Sierra Wireless, SK Teletech, Sony Ericsson, T&A Alcatel,Toshiba, Verizon, and soon to be Apple Inc.. There are also specialist communication systems related to (but distinct from) mobile phones, such as Professional Mobile Radio.

Technology


Mobile phones and the network they operate under vary significantly from provider to provider, and nation to nation. However, all of them communicate through electromagnetic radio waves with a cell site base station, the antennas of which are usually mounted on a tower, pole or building.

The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, usually not more than 5 to 8 miles (approximately 8 to 13 kilometers) away. When the mobile phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will "handoff" to various cell sites during calls, or while waiting (idle) between calls it will reselect cell sites.

Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch. The switch in turn connects the call to another subscriber of the same wireless service provider or to the public telephone network, which includes the networks of other wireless carriers. Many of these sites are camouflaged to blend with existing environments, particularly in high-scenery areas.

The dialogue between the handset and the cell site is a stream of digital data that includes digitized audio (except for the first generation analog networks). The technology that achieves this depends on the system which the mobile phone operator has adopted. Some technologies include AMPS for analog, and D-AMPS, CDMA2000, GSM, GPRS, EV-DO, and UMTS for digital communications. Each network operator has a unique radio frequency band.

The History of the Laptop Computer

In this day and age, computer technology develops so rapidly that it seems there is no end to the possibilities of the miracle machine. Computers, once monstrous behemoths that could dominate whole rooms, can now be compacted into lightweight, portable notebook systems. The laptop computer was likely unimaginable when computers were first created more than 60 years ago, but today it features incredible technology in a very small package.

The Idea Is Born

The idea of a portable, technically complete computer system was first conceived of as early as the 1970s. While the technology of the laptop would not be feasible until the next decade, researchers at Xerox were experimenting with a type of portable computer, called the Dynabook, in the late 1960s and early 1970s (Wurster 2001). The Dynabook was intended to be a type of tablet computer (with a screen that did not fold down as the screens of most modern laptop computers do) that could run on nearly eternal battery life. Unfortunately, technology in the 1970s was not advanced enough to support this idea, and the concept of the Dynabook was never developed into an operational unit.

Earliest Laptops

Portable computers first became commercially available in 1981 with the Osborne 1 system (Wilson 2006). This computer was about the size of a portable sewing machine, featured a tiny monitor, and could not be run on battery power. However, it revolutionized the business world, allowing business professionals to carry their computer data with them for the first time, even on airplanes. But due to the unwieldy size of the Osborne I and its inability to run on battery power, the system never really took off in the commercial market, though it would remain a vanguard of technological advances to come.

The first true laptop computer, which featured a flat display screen that could fold down on the keyboard, was introduced in 1982. Termed the GRID Compass, the computer featured the clamshell design that is still used for most modern laptops and could be run on battery power (Wilson 2006). However, its incredibly high price and IBM incompatibility limited its attractiveness in the commercial market, and it was used primarily by only the U.S. military and NASA.

Two other portable computers, introduced in 1983, would prove to be slightly more successful in the commercial market. The Compaq Portable and Epson HX-20 featured revolutionary changes that would make them much more viable for business use. While the Compaq system required AC power, it was the first portable computer to be compatible with the MS-DOS operating system and IBM software, allowing for ease in data transfer from desktop computers. The Epson HX-20, while fairly simple in its programming, was relatively inexpensive and could be run on rechargeable batteries.

By late 1983, the market for laptop computers was wide open, and traveling business people were hungry for improved technology. Correspondingly, this year saw the launch of one of the most popular early laptops, the Kyocera Kyotronic 85 (Wilson 2006). This product was first introduced in Japan and experienced relatively slow sales, but American computer engineers quickly saw its potential and began marketing it in the United States with substantially increased commercial success. The laptop featured an internal modem and several programs designed by Microsoft. It was also capable of running on regular AA batteries. Although it did not feature the clamshell design most common in today’s laptops, it was about the size of a standard paper notebook. The computer’s low price (as little as $300) and convenient portability made it a bestseller among journalists and correspondents.

IBM-Compatible Laptops

Despite the relative success of some early laptops and the clamor by business people for more portable computers, laptop producers encountered some difficulty gaining overall popularity for their systems that were not IBM compatible. Because IBM was the major platform for most desktop computers, it became essential that laptop computers were IBM compatible in order to promote the transfer of data from one computer to another. To fulfill this need, two IBM-compatible laptops were launched in 1986 and 1987 to moderate success (Wilson 2006). Produced by IBM and Toshiba, the units were fairly limited in their operating capabilities but they were light enough to be carried in a backpack, could be run on batteries, and included a pause feature that allowed users to resume work between sessions without restarting. While the IBM-compatible systems were useful, they were still limited in their viability and did not experience large-scale commercial success.


Laptops Experience True Success


By 1987, several laptop manufacturers had emerged on the market, and competition was fierce to produce the first, truly successful laptop computer. In that year, a contract from the United States Air Force for the purchase of 200,000 laptops was up for grabs, and computer manufacturers competed heavily to win the contract. Each company rushed to develop prototypes that would secure the deal, with Zenith Data Systems (ZDS) eventually emerging as the victor. On the strength of the contract from the Air Force, ZDS became the largest manufacturer of laptop computers in the late 1980s (Wilson 2006).

In order to capitalize on its leadership role, ZDS partnered with a Japanese equipment supplier that would speed the design and manufacturing process of its laptop computers. Soon, other laptop manufacturers followed suit and began working with Japanese equipment suppliers. However, as Japanese currency became stronger in the early 1990s, the profit margin of U.S. companies decreased, and many manufacturers began to turn to Taiwan as the major source of equipment (Wurster 2001). Companies that formed partnerships with Taiwanese suppliers (including Dell, Gateway, and Micron) quickly began to rise to leadership positions in the laptop market. By this time, laptop computers had become quite popular among business people, and suppliers rushed to furnish the growing market with lighter, faster, and more viable machines.


Apple Enters the Market


Apple Inc., while quite prominent in the desktop computer market during the 1980s, was relatively slow entering the market of laptop computers. It was not until 1989 that the company released its first portable computer, the Macintosh Portable (Wilson 2006). The computer was praised for its incredibly clear display and long battery life, but it was too bulky and heavy to be truly competitive with other available laptop computers. Because Apple had not yet provided a truly successful Macintosh laptop, several other suppliers began producing compatible machines; however, copyright law required that the user of one of these laptops must also purchase a new or used Macintosh computer to supply the necessary Mac ROM images.

While Apple was slow to enter the market and was unable to provide a truly successful laptop model on its first attempt, the company’s 1991 PowerBook series revolutionized laptop technology. Computers in the series were the vanguard of several standard features in today’s laptop computers, including the placement of the keyboard, the touchpad mouse, and built-in network adapters.

Microsoft Standardizes the Laptop

Perhaps the most significant event in the history of laptop computers was the release of the Windows 95 operating system by Microsoft in 1995 (Wurster 2001). Prior to this, operating systems for laptops varied widely, and suppliers experienced a great amount of flexibility in the design of their computers. The introduction of Windows 95 as the most prominent operating system served to standardize and stabilize most aspects of laptop design. It was also during this year that CD-ROM drives, Intel Pentium processors, and floppy disk drives became standard features on nearly all laptops. Leading laptop suppliers like Dell, Gateway, and Toshiba quickly released models that complied with the expected features of a standard laptop computer.

As technology has developed since 1995, the popularity and viability of laptop computers have greatly increased. Improved battery life, displays, processors, and network connectivity have all served to increase the ubiquity of laptop computers. Today, the average laptop computer is a far cry from the heavy, bulky portable computers of the early 1980s. Indeed, there is no telling how the laptop will continue to develop in future years as computing technology advances.
