You're making assertions which I'm not sure they're nearly as obvious and universal nowadays as you think they are. Perhaps they're still true more often than not -- but I'd assign roughly 50/50 which direction the stereotypes you gave nowadays go.

E.g. on my part I don't watch TV often, but the last time I saw in comedies businesspeople chase after their "hot young" secretaries, was when in "Friends" Rachel was chasing after her male secretary, and Chandler's female boss was chasing after him. Just a datapoint, perhaps you have more recent and more frequent "daytime TV" and romantic comedies examples?
