So what is a bookmaker?
A company that manufacturers books? A book about how to publish books?
In short, a bookmaker (also known as a “sportsbook” or a “bookie” if a person) is business/individual that offers odds on sporting events, and accepts bets and pays out winnings to bettors based on those odds.
Not limited to just sporting events, bookmakers do offer odds and accept bets on various events worldwide such as the outcomes of TV shows and political elections just to name a few.
