Betfair was set up in August 1999 by Andrew "Bert" Black and Edward Wray. Unlike fixed odds bookmakers such as William Hill, Ladbrokes and Coral, betfair is a betting exchange, allowing customers to choose whether to back a selection or instead effectively act as the bookmaker themself and lay a selection instead.
Betfair is now the World's biggest betting exchange and has revolutionised the betting industry in the process.
Betfair is now opening to Canadians for the first time in history and all Canadian residents can claim $50 free.
