Some shows go on seemingly forever: Doctor Who‘s a good example, as is The Sky At Night. Sometimes there’s a good reason: the quality of the show, interesting scripts, the fact it’s a soap opera and so on.
Then there are some shows that go on forever where it’s really hard to understand why. In the US, there’s Law and Order, which has been going on for the best part of 20 years now. Then there’s New Tricks in the UK, as well as Heartbeat and I’m sure Last of the Summer Wine is still out there somewhere. Why?
The obvious answer is ratings. The shows still get plenty of viewers. The question again though is why? Why do people watch these shows?
