Television announcer (The Chase)

At 18:59, on 13 May 1965, a television announcer alerted BBC viewers that the next programme would start within one minute.

In the distant future, Vicki Pallister, Ian Chesterton, Barbara Wright, and the First Doctor heard his announcement whilst aboard the TARDIS, via the Time-Space Visualiser they had taken from the Space Museum. (TV: The Chase)
