Microsoft has reigned the browser market for a long time, ever since it took the original Netscape browser out of the picture; there has been no competitor able to keep up with Internet Explorer. Unfortunately for end users however, the software giant has been sitting duck for about half of its lifetime, adding almost no new features since IE 6 was introduced in 2001, and until very recently, barely keeping up with security holes found in its browser.
