American and Canadian pop culture in a TL where crime dramas flop and other changes

I'm curious what the television and film landscapes in America and Canada would look like with some big changes. What would happen to TV if for some reason, crime dramas/police shows massively flopped after the 60s?

Also, what would happen if anime and tokusatsu was somewhat more popular than in OTL and regularly had theater releases in both of the two countries?
