British TV bears some similarities to American TV, yet there are two major things that separate the two industries. In the UK, networks aren’t as trigger-happy as those in the US. Showrunners are usually granted ample time to build their stories. Interestingly, these showrunners aren’t normally interested in stretching their shows for too long either. The majority of them prefer to end things on a high, so it’s rare for any TV series to jump the shark.
