I'm don't know about the rest of the world, but at least North America 
includes H.264 as one of the supported codecs now:

http://en.wikipedia.org/wiki/Advanced_Television_Systems_Committee_standards#H.264.2FMPEG-4_AVC

Of course, given that this happened after significant hardware was out 
in the field, it's questionable whether there's been much actual *use* 
of H.264 in ATSC.
