Until 2018, there was a federal ban on commercial sports gambling. But that changed with a Supreme Court ruling last year, legalizing it.
Because of state constitutions, sports betting is still not legal in many states, including Wisconsin. But the potential repercussions would impact sports fans throughout the country. Historically, gambling has had a corrosive effect on the spirit of competition, creating financial incentives for fixing games. A famous example of this issue came in the early 20th century, in what is now known as the "Black Sox Scandal."
