Lol it's hard to convey just how bad TV was after 9/11 for quite awhile. Everything was over the top sad. Also while on the topic I'm pretty sure if I recall correctly for the entire day of 9/11 every single network besides kids shows and maybe a few others like weather all were showing 9/11 coverage. You literally couldn't find a channel not rebroadcasting the news coverage besides those, it was wild.
It should be noted that the "bans" were not governmental and were carried out entirely by the private owners of radio stations. Clear Channel in particular, perhaps others.
