A group of regional sports networks (RSNs) is set to wind down, marking the demise of a once lucrative business. Despite live sports commanding the highest TV ratings, RSNs are under increasing pressure as consumers switch to streaming. Major League Baseball announced last week it would take over media distribution for 14 teams in the 2026 season. Main Street Sports, formerly Fox Sports networks, emerged from bankruptcy protection in late 2024 and faced another liquidity crunch earlier this year when MLB rights payments were due. The remaining NBA and NHL teams are yet to be determined, although some are likely to find homes with broadcast station owners acquiring local rights. The RSN model is expected to affect the future of professional sports leagues, particularly MLB, which has some of the most expensive rights fees and the most local games.
