Terry Pratchett's Going Postal is a two-part television film adaptation of "Going Postal" by Terry Pratchett, adapted by Richard Kurti and Bev Doyle and produced by The Mob, which was first broadcast on Sky1, and in high definition on Sky1 HD, at the end of May 2010.
Sky 1 has commissioned many homegrown programmes since it first started broadcasting back in 1984 but it was not until 1989 that content went beyond music and children's reprogramming.
 During the early years new game shows included a few series of "Blockbusters" and "Spellbound", along with "The Price is Right" and "Sale of the Century".
 Original dramas include "Dream Team", a series based on a fictional football team; "The Strangerers", a science fiction sitcom that was dropped after one series and never repeated; Al Murray's sitcom "Time Gentlemen Please"; and "Baddiel's Syndrome". "
Hex", another sci-fi show, proved popular but was cancelled in April 2006, and "Mile High" also proved quite popular but only lasted from 2003–2005.
 Sky One commissioned "Terry Pratchett's Hogfather" for Christmas 2006, which proved to be their most successful programme ever.
 Following that success, Sky brought out in 2008 an adaptation of "The Colour of Magic" and its second half "The Light Fantastic", and in 2010 "Terry Pratchett's Going Postal", the 33rd book in the "Discworld" series.
 Sky also co-produces "The 4400" and co-financed the first season of "Battlestar Galactica".
