When Betfair opened its doors in 1999, they were far ahead of their time with their sportsbook offering; a first of its kind, the betting exchange allowed users to create odds on events and have others take those wagers in an open exchange.
Betfair is one of the world's best known operators due to the simple fact that it is entirely different from other betting companies. Over the years, BF has become a popular betting exchange, while also offering the services of a traditional bookmaker. They are a part of the Paddy Power Betfair plc and begun offering their sportsbook in 1999. After their first successful year, they made their entrance to the online markets and quickly found themselves at the top of the betting industry. Their largest player base comes from the UK market and they also have dedicated players in Italy and Spain as well.
