Until 17 October 2011, the Commercial Public Service Broadcasters had the opportunity to apply to Ofcom to provide an additional HD service from between 28 November 2011 and 1 April 2012. Channel 5 HD was the sole applicant, with the aim of launching in spring or early summer 2012. On 15 December 2011, Channel 5 dropped its bid to take the fifth slot after being unable to resolve "issues of commercial importance". Subject to any future Ofcom decision to re-advertise the slot, the capacity will remain with the BBC and can be used by it for BBC services or services provided by a third party via a commercial arrangement. The BBC temporarily used the space to broadcast a high definition simulcast of their main Freeview red button feed for the duration of the 2012 Summer Olympics, followed by a channel from Channel 4 for the 2012 Summer Paralympics. On 13 June 2013, the BBC temporarily launched a high-definition red button stream in the vacant space.
