The Teletubbies

We learned this week that Jane Horrocks, Jim Broadbent and Fearne Cotton are to voice a new run of the hit children's TV series Teletubbies. It's estimated that around a billion children in over 120 countries have watched Teletubbies but there have been no new episodes since 2001, and the imminent return of Tinky Winky, Dipsy, Laa-Laa and Po has made news around the world. But who, or what, are the Teletubbies? And why have they proved such an enduring cultural phenomenon?

Presenter: Becky Milligan
