Celebrity Mastermind is a British television quiz show broadcast by BBC television. The show is a spin-off of the long-running quiz show Mastermind, with the exception that all the contestants are celebrities. As with the main show, John Humphrys is the host and question-master. Magnus Magnusson was quizmaster on the 2003/04 episodes featuring Jonathan Meades as winner.

Romesh Ranganathan takes charge of the back-stabbing big money game show. Can the contestants create a chain of answers and avoid the boot?

All Over the Place is a children's television programme produced by the BBC. It is similar in ways to the discontinued programme Wonderful World of Weird, however All Over the Place is not principally a game show. It features the CBBC presenters Ed Petrie, Chris Johnson, Ceallach Spellman, Richard Wisker, Johny Pitts, Barney Harwood, Naomi Wilkinson and Iain Stirling.

Celebrities discuss their own personal experiences before surprising two of their teenage fans and passing on their knowledge about the difficult subjects.

It's 30 years since CBBC started airing short links between shows. To celebrate, Hacker has brought together the finest presenters, past, present and even a new one, to reminisce and laugh at a few bloopers.
