There are three dominant television genres:
The sitcom.
The hour-drama.
And the TV movie (or movie-of-the-week, as they were once called).
Each of these of genres is formatted differently, so before you look at any format guide you'll need to decide which type of script you want to write. Recently, there's also been a resurgence of channels willing to take a risk on the lame-duck of TV genres, the half-hour drama. If you decide to go down this path, know that half-hour dramas are formatted just like hour-long dramas, but shorter. By half.
