While most of the channel's offerings are acquired from British networks such as BBC, ITV, Sky One, and Channel 4, it also airs some acquired American shows, as well as its own original programming and co-productions. (Unlike most of my network pages, I'll list programs here alphabetically)

Battlestar Galactica (American; Sci-Fi Channel)
Being Human (BBC Three)
Demons (ITV)
Doctor Who (BBC One; co-production since series 4)
Hex (Sky One)
Jekyll (BBC One; co-production)
MI-5 (BBC One)
