The world's shortest TV commercial is half a frame (one field) and lasts for 1/60 of a second. Twelve different versions of the commercial were produced, all advertising MuchMusic (a Canadian music and video TV channel), and the first was aired on 2 January 2002. The creator, producer and editor was Tharanga Ramanayake (Canada).
