Freeview HD started its "technical launch" on 2 December 2009, hosting BBC HD, and ITV HD. On 30 March 2010, Freeview HD had its official launch, and added Channel 4 HD to its broadcasts. The fourth channel hosted was BBC One HD, while the fifth slot was used for a high-definition simulcast of CBBC during the daytime and a high-definition simulcast of BBC Three during the evening. The fifth HD stream on the DVB-T2 multiplex was going to be used by Channel 5 for their HD service, but they withdrew their application to Ofcom for the slot in December 2011.
