Before 2018, the NFL fought hard to keep sports betting illegal, and that changed when the Supreme Court struck down those restrictions. ESPN’s David Purdum is one of the journalists who’ve covered the industry since that decision, and he tells us what’s changed in this new world.

PURDUM: It’s a very different landscape, because we’ve gone from fighting to basically trying to keep it in Nevada to embracing it, and in a lot of ways partnering with it, in a way that we probably would have never imagined before the ruling.

Legal sports betting rolled out in Connecticut in October 2021, with DraftKings, FanDuel and BetRivers all offering online and mobile betting. Voters in Colorado approved a sports betting measure last year, and the first online and retail books went live on Jan. 11, with more expected soon.

Maine passed a bill in April, but it took until November 2022 for the first sportsbooks to go live. Its law allows for both in-person and online sports betting, and the state’s four Native American tribes are also allowed to partner with commercial operators.

In addition to moneylines and point spreads, sportsbooks offer a variety of other types of bets. These include parlays, which are multiple bets that must win to earn a payout, and prop bets, which are based on events that can happen during a game but aren’t related to the final outcome of the game, such as how long the national anthem will last at Super Bowl LIII or what color Gatorade will get dumped on the winning coach.
