When I read the headline I assumed Microsft were getting out of the browser business, which might have made more sense.  However a new browser, Spartan is coming.

Microsoft sends Explorer into retirement

Internet Explorer — the software that launched the browser wars of the 1990s and became a symbol of the Seattle company’s former stranglehold on the tech world — is about to be ushered into retirement.

The group confirmed this week that it would not use the IE name for the new browser that it plans to ship with the next version of its Windows operating system, due later this year. The revised software, codenamed Project Spartan, is intended to catapult Microsoft beyond the Web 1.0 world for which IE was designed.
