AT&T SportsNet (ATTSN) is the name for a group of regional sports networks in the United States that are primarily owned and operated by AT&T Sports Networks, LLC (formerly Liberty Sports Holdings and DirecTV Sports Networks, LLC), a subsidiary of WarnerMedia News & Sports, which in turn is a division of AT&T's WarnerMedia. Each of the networks carry regional broadcasts of sporting events from various professional, collegiate and high school sports teams (with broadcasts typically exclusive to each individual network, although some are shown on more than one AT&T-branded network within a particular team's designated market area).
In addition to carrying team and conference-related magazine, analysis and discussion programs exclusive to each region, most of the networks (with the current exception of AT&T SportsNet Southwest) also broadcast nationally distributed sports events, documentary and entertainment programs through a programming agreement with Bally Sports, which is the successor to Fox Sports Networks, a remnant of their former ownership under their previous corporate parents.
While previously operating under the FSN name, these four networks relaunched under the brand Root Sports on April 1, 2011, coinciding with the start of the Major League Baseball regular season. On July 14, 2017, following the acquisition of DirecTV by AT&T, the networks (besides Root Sports Northwest as it is majority-owned by the Seattle Mariners and minority-owned by AT&T) were re-branded under the name AT&T SportsNet, coinciding with the second half of the 2017 Major League Baseball season. Collectively, the networks serve 13 million cable and satellite subscribers in 22 states. AT&T SportsNet master control operations are based in Atlanta, Georgia.
