The channel officially launched on 1 December 2007 although much of the programme makeup and format of the broadcasts remained the same from the trial. This new channel was nationwide and platform neutral, in that it was carried by all providers as a free to air channel. This channel, as recommended by the BBC Trust's Public Value Test, broadcast only for around nine hours a day during prime time and only showed programmes made specifically for HD. The channel would air programmes from across the BBC channels.
