I grew up during the seventies when network TV shows still put a lot of thought and effort into such things as their theme tune. It was a decade littered with memorable tracks that captured the essence of the shows they came from. Many have now become integral aspects of popular culture, leading to countless internet memes as well as becoming the ringtones of choice for many a fortysomething. However, things are very different now. You can have a staggeringly good theme for your show, but it can't possibly be longer than thirty seconds. And don’t think for a moment that viewers can listen to it again at the end, as it has now become standard practice to compress the credits into a third of the TV screen and preview what's coming next, while some link announcer spouts inanities. Mercifully, cable and streaming companies tend to treat their TV shows with greater respect. The lack of commercial advertising ensures a longer program duration and hence more focus on a theme tune. However, network TV still commands big audiences, yet hasn’t in recent years produced any TV show themes of note.
