Shock Jocks aren't a form of entertainer that are particularly in demand, though. There aren't really any new ones coming up, and all the old ones have mostly died out after Stern fled the scene and terrestrial radio began tumbling towards cutural irrelevance shortly thereafter.
The best analogy I can think of right now is that the audience for "Shock Jocks" is the pop-culture equivalent of people who stick with flip phones because they don't want to take the time to figure out how smartphones work.
"Shock Jocks" are, more than anything, a 90s phenomenon that's survived into the 21st century due to its followers being complacent and overly habitual. Anyone who is still good at that particular art has learned how to adapt those skills to other media, or they've dead-ended. For example: Seth McFarlane woulda been a great shock jock. Luckily (for him, at least), he never got stuck in radio. Jimmy Kimmel WAS in radio, but translated those skills to a much more lucrative, attention-getting medium.
Shock Jocks in the 21st century are like refugees from an alternate universe where Jerky Boys never stopped being platinum-sellers.
