Huh?
There is enough spectrum in one band 70 cm (420 - 450 MHz) alone to allow the concurrent operation of several full-blown, full-motion, color ATV (Amateur Television) stations!
'Ham' radio isn't quite limited like CB (legally, only 40 'channels' allocated) is - there are variety of 'bands' with a varying amounts of spectrum in each ...
I am not up to date at all, and wouldn't presume to describe what's available to Ham operators today--except that I'm pretty sure that the Internet enables an "operator" such as FR to buy as much bandwidth as it wants--to include, perhaps, ten video channels. And that any other operator can do likewise, simultaneously. The upshot is that the only limit on televising over the internet is trying to get an audience, not trying to get a channel allocation. And I see that as a fundamental difference--I can televise any time I want, but you don't have to watch. That's the First Amendment way. Whereas broadcast band licenses are scarce as hen's teeth.
