===== Internet =====
The 90s were a vital period for the development of the [[Internet]]. Several inventions and applications were launched to create the web as it's known today. [[Tim Berners-Lee]], an English computer scientist, released the [[World Wide Web]] to the general public on April 30, 1993.<ref>{{Cite web |title=World Wide Web (WWW) launches in the public domain {{!}} April 30, 1993 |url=https://www.history.com/this-day-in-history/world-wide-web-launches-in-public-domain |access-date=2025-01-09 |website=HISTORY |language=en}}</ref> The same year, [[NCSA Mosaic#:~:text=Mosaic, the first web browser,Mosaic appeared on the scene.|Mosaic]], one of the first widely available web browsers, was launched as the first browser to display images in line with text and not in a separate window.<ref>{{Cite web |title=Browser {{!}} Web surfing, navigation, search engine {{!}} Britannica |url=https://www.britannica.com/technology/browser#ref1036937 |access-date=2025-01-09 |website=www.britannica.com |language=en}}</ref> In 1990, [[Archie (search engine)|Archie]], the world's first search engine, was released. In the early days of its development, Archie served as an index of [[File Transfer Protocol]] (FTP) sites, which was a method for moving files between a client and a server network.<ref>{{Cite web |last=Nguyen |first=Jennimai |date=2020-09-10 |title=Archie, the very first search engine, was released 30 years ago today |url=https://mashable.com/article/first-search-engine-archie?test_uuid=01iI2GpryXngy77uIpA3Y4B&test_variant=b |access-date=2025-01-09 |website=Mashable |language=en}}</ref><ref>{{Cite web |title=What is File Transfer Protocol (FTP) meaning |url=https://www.fortinet.com/resources/cyberglossary/file-transfer-protocol-ftp-meaning |access-date=2025-01-09 |website=Fortinet |language=en}}</ref> This early search tool was superseded by more advanced engines like [[Yahoo!]] in 1995 and [[Google Search|Google]] in 1998.<ref>{{Cite news |last=Clark |first=Andrew |date=2008-02-01 |title=How Jerry's guide to the world wide web became Yahoo |url=https://www.theguardian.com/business/2008/feb/01/microsoft.technology |access-date=2025-01-09 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref><ref>{{Cite web |date=2025-01-09 |title=Britannica Money |url=https://www.britannica.com/money/Google-Inc |access-date=2025-01-09 |website=www.britannica.com |language=en}}</ref>

Following the launch of the early Internet and fiber optic capabilities to the public, a significant shift occurred. Consumers, recognizing the potential of the Internet, began to demand more network capacity. This surge in demand spurred developers to seek solutions to reduce the time and cost of laying new fiber, in order to meet the growing needs of the public.<ref>{{Cite web |title=Birth of the Commercial Internet - NSF Impacts {{!}} NSF - National Science Foundation |url=https://new.nsf.gov/impacts/internet#:~:text=Going%20public,dedicated%20infrastructure%20backbone%20in%201995. |access-date=2025-01-09 |website=new.nsf.gov |language=en}}</ref><ref>[https://www.scienceandmediamuseum.org.uk/objects-and-stories/short-history-internet “A Short History of the Internet.”] ''National Science and Media Museum'', 3 Dec. 2020, www.scienceandmediamuseum.org.uk/objects-and-stories/short-history-internet. </ref><ref name=":3">{{Cite web |title=Internet Commercialization History |url=https://internethistory.org/commercialization/ |access-date=2025-01-09 |website=History of the Internet |language=en-US}}</ref>

In 1992, [[David R. Huber|David Huber]], an optical networking engineer, joined forces with entrepreneur [[Kevin Kimberlin]]. Together, they laid the foundation for a new era in telecommunications with the birth of [[Ciena|Ciena Corporation]].<ref name=":3" /><ref>Hirsch, Stacey (February 2, 2006).

Prominent [[website]]s launched during the decade include [[IMDb]] (1993), [[eBay]] (1995), [[Amazon (company)|Amazon]] (1994), [[GeoCities]] (1994), [[Netscape]] (1994), [[Yahoo!]] (1995), [[AltaVista]] (1995), [[AIM (software)|AIM]] (1997), [[ICQ]] (1996), [[Hotmail]] (1996), [[Google]] (1998), [[Napster]] (1999). The pioneering [[peer-to-peer]] (P2P) file sharing internet service [[Napster]], which launched in Fall 1999, was the first peer-to-peer software to become massively popular. While at the time it was possible to share files in other ways via the Internet (such as [[IRC]] and [[USENET]]), Napster was the first software to focus exclusively on sharing [[MP3|MP3 files]] for [[music]].

*On 6 August 1991, [[CERN]], a pan-European organization for particle research, publicized the new World Wide Web project.<ref name="wwwinvent">{{Cite news|title=How the Web Was Spun|url=http://www.time.com/time/80days/910806.html|last=Grossman|first=Lev|date=31 March 2003|work=Time Magazine|archive-url=https://web.archive.org/web/20090625000847/http://www.time.com/time/80days/910806.html|archive-date=25 June 2009|quote=Berners-Lee's computer faithfully logged the exact second the site was launched: 2:56:20&nbsp;pm, 6 August 1991.|access-date=19 July 2009|url-status=dead }}</ref> Although the basic applications and guidelines that make the Internet possible had existed for almost two decades, the network did not gain a public face until the 1990s.
*Advancements in [[Modem|computer modems]], [[Integrated Services Digital Network|ISDN]], [[cable modem]]s, and [[Digital subscriber line|DSL]] led to faster connections to the Internet.
*Businesses start to build [[e-commerce]] websites; e-commerce-only companies such as [[Amazon.com]], [[eBay]], [[AOL]], and [[Yahoo!]] grow rapidly.

*Driven by mass adoption, consumer [[personal computer]] specifications increased dramatically during the 1990s, from 512 KB RAM 12&nbsp;MHz [[White box (computer hardware)|Turbo XTs]] in 1990,<ref>{{cite book|url=https://books.google.com/books?id=dzAEAAAAMBAJ&pg=PA5|title=InfoWorld Jan 8 1990|publisher=InfoWorld Media Group, Inc.|date=8 January 1990}}</ref> to 25–66&nbsp;MHz [[Intel 80486|80486]]-class processor<ref>{{cite web|url=http://winsupersite.com/article/commentary/blast-buying-computer-1995-141723|title=Blast from the Past: Buying a Computer in 1995|date=27 December 2011|access-date=8 May 2015|archive-url=https://web.archive.org/web/20150518080723/http://winsupersite.com/article/commentary/blast-buying-computer-1995-141723|archive-date=18 May 2015|url-status=dead}}</ref> to over 1&nbsp;GHz CPUs with close to a [[gigabyte]] of RAM by 2000.

*[[Year 2000 problem|Y2K]] spread fear throughout the United States and eventually the world in the last half of the decade, particularly in 1999, about possible massive computer malfunctions on 1 January 2000. As a result, many people stocked up on supplies for fear of a worldwide disaster. After significant effort to upgrade systems on the part of software engineers, no failures occurred when the clocks rolled over into 2000.
*The [[P5 (microarchitecture)|first Pentium microprocessor]] is introduced and developed by the [[Intel|Intel Corporation]].
*Email becomes popular; as a result, [[Microsoft]] acquires the popular [[Outlook.com|Hotmail]] webmail service.
*[[Instant messaging]] and the [[contact list|buddy list]] feature becomes popular. [[AOL Instant Messenger|AIM]] and [[ICQ]] are two early protocols.
*The introduction of affordable, smaller [[satellite dish]]es and the [[DVB-S]] standard in the mid-1990s expanded satellite television services that carried up to 500 television channels.
*The first MP3 player, the [[MPMan]], is released in the late spring of 1998. It came with 32 MB of [[flash memory]] expandable to 64 MB. By the mid-2000s, the MP3 player would overtake the CD player in popularity.
*The first [[GSM]] network is launched in Finland in 1991.
*[[Digital single-lens reflex camera]]s and regular [[digital camera]]s become commercially available. They would replace film cameras by the late 1990s and early 2000s.
*[[IBM]] introduces the {{convert|1|in|mm|adj=on}} wide [[Microdrive]] hard drive in 170 MB and 340 MB capacities.
*[[Apple Computer]] in 1998 introduces the [[iMac]] all-in-one computer, initiating a trend in computer design towards translucent plastics and multicolour case design, discontinuing many [[legacy system|legacy technologies]] like [[serial port]]s, and beginning a resurgence in the company's fortunes that continues to this day.
*[[Optical disc drive|CD burner]] drives are introduced.
*The [[CD-ROM]] drive became standard for most personal computers during the decade.
*The [[DVD]] media format is developed and popularized along with a plethora of [[memory card|Flash memory card]] standards in 1994.
*[[Pager]]s are initially popular but ultimately are replaced by mobile phones by the early-2000s.
*Hand-held [[satellite phone]]s are introduced towards the end of the decade.
*The [[24-hour news cycle]] becomes popular alongside the outbreak of the [[Gulf War]] between late 1990 and early 1991, and is solidified with CNN's coverage of [[Desert Storm]] and [[Operation Desert Shield (Gulf War)|Desert Shield]]. Though CNN had been running 24-hour newscasts since 1980, it was not until the Gulf War that the general public took notice, and others imitated CNN's non-stop news approach.<ref>{{cite web|url=http://birminghamskews.com/post/4544141336/this-truly-is-our-story|title=This truly is our story|access-date=3 June 2011|url-status=dead|archive-url=https://web.archive.org/web/20120324225107/http://birminghamskews.com/post/4544141336/this-truly-is-our-story|archive-date=24 March 2012 }}</ref>
*[[Portable CD player]]s, introduced during the late 1980s, became very popular and profoundly impacted the music industry and youth culture during the 1990s.
