ITV3 is a British free-to-air television channel owned by ITV Digital Channels, a division of ITV plc. The channel was first launched on Monday 1 November 2004 at 9 pm, replacing Plus (previously known as G+). ITV3 is the sixth-largest UK television channel by audience share and the largest after the five main terrestrial services, the position which was previously held by its sister station ITV2. The channel is primarily devoted to repeats of ITV dramas, and including sequential reruns of Agatha Christie's Poirot, Classic Coronation Street, Classic Emmerdale, Heartbeat, Inspector Morse and A Touch of Frost, amongst others, as well as formerly showing repeats of Kojak, Numb3rs, Columbo, Cagney & Lacey and The Bill, but occasionally shows popular factual programming and is also used as an overflow location for ITV's sports coverage.
