(Reuters) -Walt Disney's ESPN, Comcast-owned NBCUniversal and Amazon.com have clinched the rights to carry National Basketball Association games in a reported $76 billion deal.

The NBA said on Wednesday it rejected an offer from Warner Bros Discovery's TNT Sports division, ending a four-decade relationship with the media company.

A spokesman for TNT Sports could not immediately be reached for comment.

Analysts have said that winning telecast rights require a huge financial commitment considering the cost as well as the fees associated with production.

About 75 regular-season games will be on broadcast TV each season, up from the minimum of 15 games under the current agreement, NBA said.

"Our new global media agreements with Disney, NBCUniversal and Amazon will maximize the reach and accessibility of NBA games for fans in the United States and around the world," said NBA Commissioner Adam Silver.

"These partners will distribute our content across a wide range of platforms and help transform the fan experience over the next decade."
