Amazon.com Inc.’s Prime Video has begun offering 16 regional sports networks as a $20-a-month addition to its regular streaming service in a deal with channel-owner Main Street Sports Group.

Main Street owns 16 regional sports networks and televises professional baseball, hockey and basketball games in cities from Miami to Los Angeles. The new offering, first announced last year, continues a turnaround for Main Street, which nearly shut down in 2023 under the pressure of substantial debt and the loss of cable-TV customers migrating to streaming services.
