The NBA opened the window for its exclusive media rights negotiations with Disney and Turner on Saturday, sources told Tom Friend of Sports Business Journal.

The window lasts through April 22.

The three sides are roughly 75% in agreement on a new deal, according to sources.

The Emirates NBA Cup (previously known as the In-Season Tournament) is expected to be bundled into Disney and Turner packages.

Amazon and Apple are expected to pursue media rights once the window closes, with Amazon looking for the league's national streaming rights.

NBC is also expected to be included in the league's linear broadcast package.

League executives believe that the overall media rights deal will be worth between $60 billion and $72 billion, with negotiations to be wrapped up by July.
