The horror genre continues to be a major draw for audiences in movie theaters and on streaming. Most discussion of horror, however, is usually limited to movies, as there are far fewer TV shows in the genre that manage to break through. Though the 2000s was somewhat barren when it came to horror on the small screen, this changed in the 2010s. American Horror Story has been going strong now since 2011, for example, and the cancelled Channel Zero ran for four seasons starting in 2016. The Walking Dead universe also remains popular.
