Nearly half of the teams in the NFL have signed sponsorship deals with FanDuel, the daily fantasy sports website.
The announcement on Wednesday adds to the roster of professional sports sponsorships for FanDuel. It already had a deal with the NBA, which received an ownership stake in the company. Major League Baseball and the NHL have deals with a competitor, DraftKings.
Daily fantasy sports sites allow fans to win — and lose — money based on the results of games even in places where sports gambling is usually illegal.
Sports leagues that have traditionally had a zero tolerance policy toward gambling are more accepting of daily fantasy sports sites because it fuels interest in the games.
