It's right about that time of the year when the networks proudly announce what shows they've ordered for the upcoming season. And while it's easy to get excited about the new crop of television shows, it's important not to put the cart before the horse, because there are tons of interesting plot ideas, but only so many spots on each of the major cable networks.
More often than not, fun and innovative shows meet their demise before they even have an opportunity to cultivate a loyal audience. That's why there's a significant group of viewers who only give a show a chance if it gets past the first season -- they've been hurt too many times before, and they're not going to risk getting emotionally invested in a show that will most likely get cancelled in its first season.
That said, just as there are plenty of shows that are unfairly axed early on, there are others that are virtually guaranteed a long and fruitful life. A subset of these are actually high quality, or happen to have a close relationship to a show that is already successful.
Whatever the reason, these are the television shows that are most likely to be renewed fairly quickly.
