Talk radio / podcasting / Youtube talking heads – whether Howard Stern, local “zoo in the morning” or Joe Rogan or whoever, are similar to stand up comedians in a number of ways, partly scripted comedy, partly improvisational theatre, “guys laughing together so you can laugh with them”, likely has more in common with stand-up comedians than with your local priest cracking a joke during a sermon.
So I would put those broadcasters in the same class as stand-up comedians.
