The National Lottery Live
BBC1, 19 November 1994
A one-off, hour-long game show in which the winner got to press the button to start the first ever UK National Lottery draw.
The title was retained for subsequent lottery shows (hosted, starting the following week, by Anthea Turner), but the game show format only appeared in the first one.
This was the last UK game show (indeed, almost the last UK TV show of any kind) to muster an audience in excess of 20 million. Discounting football matches and royal funerals, only three shows since then have achieved a higher audience than this- Princess Di being interviewed on Panorama, and two episodes of Only Fools and Horses.
