Putting money on the outcome of sports is one of the most popular forms of gambling. While the origin of sports betting is uncertain, it has been around for hundreds of years. In fact, people have been placing bets on the outcome of sporting events long before they were considered sports. Some sources suggest that wagers were first placed during the Ancient Greek period, while others point to evidence of betting practices even prior to that period. Whatever the case, sports betting has become a big business, and online bookmakers are making the process of placing wagers more convenient than ever.
