In 1919, professional gambler Joseph Sullivan paid eight members of the Chicago White Sox — Oscar Felsch, Arnold Gandil, Shoeless Joe Jackson, Fred McMullin, Charles Risberg, George Weaver, and Claude Williams — around 10,000 dollars each to fix the World Series against the Cincinnati Reds. It would mark one of the most infamous incidents of match-fixing in history.

New York’s sportsbooks had a slow start this week, but revenue has been good so far, and the industry continues to grow in a state with strong gaming aversions.

In addition, the state’s four Native American tribes can partner with operators to offer sports betting at their casinos.

The NHL hasn’t taken a public position on legal sports betting but has signed sponsorship agreements with William Hill and MGM Resorts International that include data partnerships. In Nevada, the NHL’s expansion Vegas Golden Knights have a retail sportsbook in partnership with Caesars and a mobile app with BetMGM.

But in the vast majority of US markets, only Tier 2 bets must use official data; Tier 1 wagers can be graded without it, and odds on those outcomes can shift on their own.
