Commercial Breakdown is a light entertainment show that shows humorous television advertisements from around the world and ran from 29 December 1989 to 3 August 2008 and aired on BBC One. British adverts were initially not allowed because of the BBC's Royal Charter (advertising is completely forbidden on the BBC), but were later permitted provided they were not currently being broadcast. Many of the adverts were international, which means they were not selling items on the British market.
