Google announced Tuesday that its Chrome browser will stop supporting the H.264 codec in a couple of months and will support its own WebM and Ogg Theora technologies instead. The announcement set off a firestorm. Some contended the move is a step backward for openness; others speculated that it might create a roadblock for adoption of the HTML5 standard; a few questioned whether or not the move would adversely impact adoption of the Chrome browser. A Microsoft evangelist posted a blog entry criticizing Google’s move, but Mozilla and Opera expressed their support.
