CBBC (Short for Children's BBC) is a British free-to-air children's television channel operated by the BBC. Launching on 11 February 2002 as a spin-off from the BBC's children's strand of the same name, CBBC broadcasts for fourteen hours per-day from 7:00 a.m. to 9:00 p.m. on Freeview, cable, IPTV and digital satellite. CBBC is primarily aimed at viewers 6 to 12 years old; a sister channel known as CBeebies serves a younger audience. CBBC was named Channel of the Year at the Children's BAFTA awards in November 2008 and 2015. The channel averages 300,000 viewers daily.

The channel originally shared bandwidth on the digital terrestrial television platform with BBC Knowledge, and later BBC Three, necessitating that CBBC sign off at 7:00 p.m. daily. Beginning on 11 April 2016, following the closure of the linear BBC Three television service, CBBC extended its broadcast day by two hours.

On 22 August 2008, the BBC announced that the channel would be available live on its website from 16 September.[5] CBBC's reach further expanded with the addition of the channel on the Sky line-up in the Republic of Ireland on 12 May 2011.[6] Since 27 March 2013, CBBC has been carried by the British Forces Broadcasting Service (BFBS), sharing a channel with BBC Two.
