One of my middle schools did both Channel 1 and a closed-circuit thing, so that killed a good 45 minutes right at the beginning of the day. The kid who did the closed-circuit show was yanked off the air and severely punished for making fun of me over the air, for the whole school to hear. I was mortified beyond description. This was middle school, too, so it was quite a bit more socially damaging than it would have been just a few years prior.
