Five HD was due to launch during 2010 but was unable to reach 'key criteria' to keep its slot. Spare allocation on multiplex B was handed over to the BBC, two years from the date when it was anticipated that further capacity on multiplex B would revert to the control of the BBC Trust. On 3 November 2010, BBC One HD launched on Freeview HD. Initially it was available in addition to the existing BBC HD channel, which continued to show the "best of the rest" of the BBC in HD. However, BBC HD was replaced by BBC Two HD on 26 March 2013.
