First commercial shown on TV in Britain

The first commercial shown on TV in Britain was for Gibbs S R Toothpaste and was transmitted at 8.12 pm on Sept 22 1955 during a variety show hosted by Jack Jackson.
Viewers saw a tube of toothpaste embedded in a block of ice and a woman called Meg Smith brushing her teeth in the approved manner, "up and down and round the gums".
The immaculate tones of Alex Macintosh delivered the newly-minted slogan: "It's tingling fresh. It's fresh as ice. It's Gibbs SR toothpaste."
The commercial owed its prime placing to chance. The Gibbs advertisement had come first in a lottery drawn with 23 other advertisements, including those for Guinness, Surf, National Benzole, Brown & Polson Custard and Summer County Margarine.
