Let's see the facts :
- Apple loves HTML5 and H.264, but hates Flash.
- Microsoft loves HTML5 and H.264 -- even declaring H.264 the default codec in Internet Explorer 9 -- and tolerates Flash.
- Apple and Microsoft belong to a patent pool known as MPEG-LA that licenses the code for H.264. Google would have to pay to support H.264.
- Firefox loves HTML5, tolerates Flash, supports WebM, but can't afford to pay the royalties for H.264.
- Google loves HTML5 and WebM, builds Flash into its browser, but hates H.264.
- Google may (or may not) hold royalty-free patents to WebM.
My conclusion ?
will celebrate the day the Web becomes H264-free,
if it happens this century.
