It was born in August 2001 and its name is Internet Explorer 6 (IE6). That same name has been associated with lack of updates, unpatched browser vulnerabilities and disregard for internet standards. Web developers loath the name and it was the reason that a lot of users (at least those in-the-know) jumped ship and moved to Firefox.
Surprisingly, and according to Microsoft, 12% of online users are still using IE6 almost 10 years later. This has led Microsoft to start a campaign to rid the world from the archaic browser and has begun a countdown with the goal to drop its usage to below 1%. Beyond posing a security risk to those using IE6, it also keeps pressure on web developers to go out of their way to make websites work with the beaten and broken old browser.
