>Plus I've never had a tv ad infect my tv and stop it from going to any other channel but CMT.

Funny story...there's a regional sports network who shows a 5-10sec image of their logo at the end of ad-blocks. When the channel was watched through the cable boxes provided by our local TV provider, the box would freeze. Either the logo image would be stuck and only audio would continue or audio would stop and video continue.

Not exactly the network's fault (we figured out that the compression they used lead to a buffer overflow in the cable box's decoding logic and figured out how to encode crash inducing video) but it was still annoying.

I am rather sure that malicious use of TV broadcasting would be cause for FCC to withdraw the broadcasting license for the company.

TV broadcasting is a very heavily regulated industry.

Their broadcast wasn't malicious, they can't exactly guarantee that the decoding logic baked into the firmware of, what I'm sure, were knockoff-brand cable boxes won't cause something silly to happen.
