Channel 5 is a television network that broadcasts in the United Kingdom. Launched in 1997, it is the fifth and final national terrestrial analogue network to launch. Originally called Channel 5, the station rebranded itself as Five in 2002. After his purchase of the station from RTL on 23 July 2010, Richard Desmond announced plans to invest more money in programming and return to the name Channel 5 with immediate effect, prior to an official relaunch. Since this announcement, the on-air identity has retained the 'Five' logo and digital on-screen graphic (DOG) but continuity announcers have referred to "Channel Five". The official new identity as Channel 5 will be reflected on-screen from January 2011 with the new logo replacing the present branding.

The channel is a general entertainment channel, with internally commissioned shows such as The Gadget Show and Fifth Gear appearing alongside numerous international programmes such as CSI: Crime Scene Investigation, Neighbours and Home and Away. The channel has historically had the lowest audience of Britain's five terrestrial television channels, with a viewing share of around 5%.
