The Philadelphia 76ers have become the first team in the four major U.S. sports to sell an ad on a jersey.

Earlier this year the NBA announced that teams will have individual company’s logos on their jerseys starting in the 2017-18 season

The 76ers announced Monday morning that ticket company StubHub will have its logo on the team’s jerseys beginning in the NBA’s three-year pilot program for ads on jerseys.

Sources with knowledge of the deal say the team has sold all three seasons at $5 million a year, with the option to extend the contract with StubHub should the league continue to allow the 2½-by-2½-inch logo patch to be on the jerseys in the future.
