You are right about that, azumaga. We have entered a day where - with only a very few exceptions - programming is no longer truly "mass media." There are so many channels and so much programming available, and so many different platforms to utilize that even a big hit show has a relatively paltry share. Never again will we see the likes of a 'shared' show like The Brady Bunch or M*A*S*H or All In The Family or even Seinfeld. You know, the kind of show that everyone of a certain age watched.
This happened long ago with radio in that there is no single defining station for a generational group anymore. At this point, it's hard to imagine how it was for the audience of WABC or WLS or WRKO or KHJ back in the 60s. Back when most everyone you knew that was at or near your age listened. When you'd go to the beach and 3/4 of the radios were tuned to the same station. And, almost everyone enjoyed it. In my case, my dad listened too.
We've become very fragmented now. Perhaps that's just a function of having a plethora of choices and it's a good thing in the interest of variety. But that would be a bit rosy. For so much fragmentation, radio has become very vanilla and TV has an awful lot of crappy programming. Programmers are trying too hard to hit a specific demo and too often miss the target and the dart board in the process. The idea of making something so good that everyone will watch or listen is long forgotten. With it, a lot of the qualities that went into fine programming are gone too. It's become somewhat of a lost art to produce a 'crowd pleaser'. Which is how we come up with something like "Chopping Block" whom nobody has ever heard of.
