History
On 1 October 2008, G4 Media announced that a British version of G4 would launch, in partnership with ITV plc.

The channel was launched on 30 June 2009, with an episode of Attack of the Show! being the first programme to air.

On 30 June 2010, a year after it's launch, an HD simulcast and a +1 feed were introduced.

On 22 June 2014, it was confirmed that the channel would be ceasing operations on 31 July 2014, after ITV declined to renew the contract for the channel, citing low ratings.

The channel ceased broadcasting on 31 July 2014 at 3:59 pm BST, with an episode of X-Play being the final programme to air. The channel's SD and HD feeds were replaced by a +1 time-shift feed and an HD simulcast of CITV, while it's +1 feed was replaced by a +2 time-shift feed of ITV.
