NEWARK — The FIFA men’s World Cup final is still four days away, but already, widespread efforts are well underway to take advantage of the historic groundswell in U.S. fan interest in soccer.

Domestically, Major League Soccer stands at the forefront of that push. This week, the league unveiled a promotional campaign, “Thanks World, We’ll Take It From Here,” that is described as the largest coordinated marketing effort in league history.

The campaign features on-field stars such as Inter Miami’s Lionel Messi and Real Salt Lake’s Diego Luna, but also high-profile team owners such as LAFC’s Magic Johnson and Austin FC’s Matthew McConaughey. Beyond the marketing, MLS and the individual clubs are providing free tickets and Apple TV access to first-time attendees to help drive further fan adoption of the league.

MLS commissioner Don Garber is scheduled to speak further Thursday regarding the “Thanks World” campaign and the league’s resumption of play after pausing for the World Cup.

“As the World Cup inspires new fans, our clubs and communities are ready to welcome them,” said MLS EVP and chief business officer Camilo Durant.
