Google has decided to throw its weight behind WebM, the new more "open" video format that competes with Apple's H.264.
In a post a month or so ago, Google announced that future versions of Chrome will drop support of H.264 in favour of WebM.
Of course, Microsoft wont play ball and build WebM into IE9 (their upcoming latest browser), prompting Google to create an Internet Explorer 9 compatible plugin to enable WebM playback in that browser.
Meanwhile, Microsoft has seemingly put their muscle behind H.264, announcing their Extension for Chrome that enables H.264 playback in that browser.
So Microsoft is making extensions for Chrome to enable a feature Google left out, and Google is making plugins for IE that Microsoft left out... Why aren't they both just working on their own damn browsers?
Thanks to Google Operating System for the story.
