I used to care about the TV upfront and the announcement of new fall series — and not just because I used to be a TV critic. Now I couldn’t care less. That has been the case for a few years. But it’s even more the case now because I simply wait for the public to tell me what the hits are and then I might watch those; the rest will just fade away. The irony in that is that in a post-blockbuster economy, TV is all the more dependent on blockbusters. Television is, indeed, becoming more like the movie industry, as The Times notes today. Oh, there will always be big hits. But it’s going to get harder and harder to count on them.
