History of Internet Browsers

The tool that we use to browse our favorite websites has a (relatively) long and rich history rife with battles for market shares and dominance. This is a look into the past major events in the web browser industry.

1991 worldwide web browser is released
worldwide web, renamed to Nexus to avoid confusion with the www system, was the first graphical web browser and WYSIWYG HTML editor.

It was developed by Tim Berners-Lee, inventor of the web.


1993 Mosaic is released
Mosaic is credited with popularizing the internet and introducing the web to the public.
Contemporaries such as Internet Explorer and Firefox still use many of the graphical user interface (GUI) characteristics of Mosaic such as a top-oriented actions bar that provides basic browsing functionalities.

1994 Netscape is formed
Marc Andreessen – lead software engineer of Mosaic- ventures out on his own, forming Netscape and releasing the first commercial web browser: Netscape Navigator.


1995 Internet Explorer, 1st Browser War
Microsoft answers the released of Navigator with its own browser, called Internet Explorer, effectively starting off the first browser war for market dominance.


1996 Opera is released to the public
Telenor, the largest Opera to the public. Two years later, it tries to grab a hold of the internet-enabled handheld device market, starting a port of Opera to mobile device platforms.


 1998 Mozilla is formed
Nerscape starts the open source Mozilla project to develop the next generation of Communicator. It becomes evident that a project built around the existing source code was difficult, so focus shifts to building from scratch.

1998 Netscape’s browser goes open source
Losing traction over Internet Explorer, Netscape decides to release the source code of communicator in the hopes of becoming a popular open source project.


2002 IE usage reaches dominating proportions
Microsoft’s Internet Explorer reaches a 95% share, having advantage of being bundled with the Windows operating system. The first browser war ends with IE being the triumphant browser.


2003 Apple’s Safari makes its debut
Apple joins the scene with the released of Safari. It introduces a solid layout engine called Webkit which has been adopted into many mobile devices including Google and Nokia phones.


2004 Firefox 1.0 is released & 2nd Browser War
Firefox 1.0, already with huge following of early adopters via their beta releases, enters the stage. The second browser war starts, indicated by a slipping market share of Internet Explorer. Firefox comprises 7.4% of browsers being used by the end of the year.

2006 Internet Explorer 7 is released
Five years after IE 6, Microsoft releases version 7 of their browser, adopting some features from its open source competition (firefox) such as tabbed browsing and anti-phising protection.


2008 – Present -  Google Chrome, Browse War intensifies
Google launches its own web browser, entering into the browser battles in the market share, Lightweight. Fast, and surprisingly stable compared to early releases of other web browsers, the second browser war gains another strong competitor.

The Top Ten Computer Virus

1. ILOVEYOU - (2000) One of the most widespread and rapidly spreading viruses ever, the ILOVEYOU virus spread via e-mail, posing as an executable attachment sent by a friend from the target's contact list.
2. Code Red - (2001) IIS on Windows servers were the target of this virus. It also launched denial of service (DoS) attacks.
3. Nimda - (2001) Nimda used seemingly every possible method to spread, and was very effective at doing so. Nimda is notable for being one of the fastest spreading and most widespread viruses ever.
4. Melissa - (1999) The Melissa virus is notable because it is a Word macro virus. It cleverly spread via e-mails sent to contacts from the infected users' address books.
5. Sasser - (2004) Sasser exploited a buffer overflow and spread by connecting to port 445 on networked Windows systems. The chaos caused was possibly the worst ever, as systems restarted or crashed.
6. The Morris Internet Worm - (1988) The grandfather of computer worms, the Morris worm infected Unix systems and was notable for its "accidental" virulence.
7. Blaster - (2003) Blaster exploited a Windows operating system vulnerability and let users know of its presence with a system shutdown warning.
8. SQL Slammer - (2003) This tiny virus infected servers running Microsoft's SQL Server Desktop Engine, and was very fast to spread.
9. Elk Cloner - (1982) Despite Apple's marketing that their systems are less prone to viruses that was not always the case. Notable as possible the first personal computer virus, Elk Cloner infected the boot sector of Apple II floppies.
10. Creeper - (1971) This is noted as possibly the first ever computer virus. It infected computers on ARPANET. Mostly harmless, the concept of Creeper has infected the minds of rogue programmers through today.
