But aren't most prime time TV shows shot on film? If
yes, then 24p might be useful for a lot of TV material.

Since 480 at 60p and 720 at 24p require similar
transmission bandwidths, I suppose there's that
tradeoff to consider. I suspect that Doug would have
loud objections to transmitting his favorite games
as 480 60p rather than 720 60p or 1080i.
I suppose what will happen is that as more and more
higher quality TVs get out there in the viewing
public's homes, the networks will gravitate to higher
quality transmissions. I doubt any network would like
to be known as the network with softer images.
