Outside of the debate on the future of Flash and Flash video on the Internet is a separate but related battle over the video standard that will be supported by HTML5. On one side of the battle line is Firefox and Opera which has pledged support for the Ogg Theora video standard, and on the other side is Apple which has been pushing for H.264. Apple is no longer alone in this fight and now has an unlikely ally in Microsoft which announced on Thursday that IE 9 will support H.264 for HTML5 video. Ogg supporters are understandably disappointed with this decision as the two computing giants may now have the combined power to squash Ogg Theora support in these other browser platforms. Look for things to get messier before they get better as Google is expected to debut its own On2-derived V8 video protocol at Google I/O next month.
