Root Sports Northwest is a privately owned regional sports network headquartered in the US and owned by the Seattle Mariners. Founded in 2010, the company employs approximately 100 individuals and reported $64.4M in revenue as of 2023. As a tier 2 media tech buyer, its primary product offerings include broadcast television and radio.
ROOT Sports Northwest aired its final broadcast on September 28, 2025, covering the Seattle Mariners' regular season finale against the Los Angeles Dodgers. This event marked the conclusion of more than three decades of regional sports television in the Pacific Northwest, with the Mariners officially exiting the regional sports network business. The club will hand over distribution of its game telecasts and streaming to Major League Baseball beginning in 2026. This follows earlier news from September 26, 2025, that the Mariners planned to shutter ROOT Sports at the end of 2025, having become sole owners of the network after purchasing the remaining stake from Warner Bros.
