The regulations haven't changed much in the last 40 years, just the pushing of the limits. There are actually two sets one for broadcast such as cable or over the air tv and premium such as HBO. Broadcast has been pushing the limits of what is allowed for the last 20 years or so but it is up to the FCC to do the enforcement, but that is one agency that has more to enforce than they have people to handle enforcement.
But this is just my $0.02.
