Nationwide

Nationwide was a British television programme. The Third Doctor was a guest on the show during the conflict with General Carrington and acquired a security badge. In 1976, the Seventh Doctor made several copies of the badge so that Broadsword and Plasticine could enter the BBC Television Centre unimpeded and stop the Vardan invasion. (PROSE: No Future)
