The channel formerly served as the regional cable broadcaster of the NBA's Denver Nuggets and the NHL's Colorado Avalanche, losing the broadcast rights in 2004 when the owner of both teams, Stan Kroenke, launched the competing regional sports network Altitude Sports and Entertainment. The station also served as the regional home of select Western Hockey League broadcasts, beginning with the 2009–10 season and ending with the 2014–15 season. The network was previously the home of Denver Pioneers hockey and men's and women's basketball, until Altitude Sports and Entertainment took over coverage beginning with the 2016–17 season. Additionally, the channel served as the official TV home of the Colorado Buffaloes until 2012, producing and airing all football and men's basketball games not picked up by national networks, as well as select other sporting events and a heavy amount of insider programs. The creation of the Pac-12 Network ended the Buffs' longtime relationship with the network, though re-airs of some football and basketball games continue to air. Colorado High School Activities Association football was also a network staple until Altitude took over broadcasting rights beginning with the 2013 season. On May 23, 2017, it was announced that the network had acquired the regional cable rights to the new Vegas Golden Knights NHL expansion team. These telecasts are available in all of Nevada, and parts of Arizona, and California, including all of San Bernardino County, as well as Utah, Wyoming, and Idaho. The games are also made available on sister network Root Sports Northwest in northern Idaho and Montana. In June 2018, AT&T SportsNet acquired rights to the newly-relocated Las Vegas Aces of the WNBA. Since at least 1990, a subfeed of AT&T SportsNet Rocky Mountain has been operated in the state of Utah that televises Utah Jazz basketball games. The Utah subfeed is available in the entire state of Utah and select areas of Idaho and Wyoming. Jazz games produced by AT&T SportsNet Rocky Mountain are also available in Idaho and Montana on sister-network Root Sports Northwest. The sub-feed was originally known as Prime Sports Intermountain West, later becoming Fox Sports Utah and Root Sports Utah. Currently the Utah subfeed does not have any different on-air branding from the main network. The most recent carriage deal with the Jazz was an exclusive 12-year agreement signed on October 20, 2009, ending the team's broadcasts on KJZZ-TV (channel 14).
