IE Drops Like a Rock, Eroded by Chrome and Firefox.
Internet Explorerís dominance on the browser market has been weakening constantly since Mozillaís open source browser started getting traction with users. And with the advent of Google Chrome, IEís share loss only became steeper. Statistics offered by Janco Associates reveal that in February 2010, Internet Explorer has dropped under 65%. Over the past four years, the release of Internet Explorer 7 and Internet Explorer 8 did nothing to halt IEís crumbling market share.
