The Calgary Flames are a professional ice hockey team based in Calgary. The Flames compete in the National Hockey League (NHL) as a member of the Pacific Division in the Western Conference. They are the third major professional ice hockey team to represent the city of Calgary, following the Calgary Tigers (1921–1927) and Calgary Cowboys (1975–1977). The Flames are one of two NHL franchises based in Alberta, the other being the Edmonton Oilers. The cities' proximity has led to a rivalry known as the "Battle of Alberta". Atlanta Flames (1972–1980) Main article: Atlanta Flames Tom Lysiak celebrates with teammates after a goal against the Colorado Rockies. From 1972 to 1980, the Flames were based in Atlanta. The Flames were the result of the NHL's first pre-emptive strike against the upstart World Hockey Association (WHA). In December 1971, the NHL hastily granted a team to Long Island – the New York Islanders – in an attempt to keep the WHA's New York Raiders out of the recently completed Nassau Veterans Memorial Coliseum. Needing another team to balance the schedule, the NHL awarded a team to the Atlanta-based group that owned the National Basketball Association's Atlanta Hawks, headed by prominent local real estate developer Tom Cousins. Cousins named the team the "Flames" after the fire resulting from the March to the Sea in the American Civil War by General William Tecumseh Sherman, in which Atlanta was nearly destroyed. They played home games in the Omni Coliseum in downtown Atlanta. The Flames were relatively successful early on. Under head coaches Bernie "Boom Boom" Geoffrion, Fred Creighton and Al MacNeil, the Flames made the playoffs in six of eight seasons in Atlanta. In marked contrast, their expansion cousins, the Islanders, won only 31 games during their first two years in the league combined. However, this success did not carry over to the playoffs, as the Flames won only two postseason games during their time in Atlanta.

Despite the on-ice success, the Atlanta ownership was never on sound financial footing. Longtime general manager Cliff Fletcher said years later that Cousins' initial financial projections for an NHL team did not account for the WHA entering the picture. The Flames were also a poor draw, and never signed a major television contract. In 1980, Cousins was in considerable financial difficulty and was forced to sell the Flames to stave off bankruptcy. With few serious offers from local groups, he was very receptive to an offer from Canadian entrepreneur (and former Oilers owner) Nelson Skalbania. He was fronting a group of Calgary businessmen that included oil magnates Harley Hotchkiss, Ralph T. Scurfield, Norman Green, Doc and Byron Seaman, and former Calgary Stampeders great Norman Kwong.[5] A last-ditch effort to keep the team in Atlanta fell short, and Cousins sold the team to Skalbania for US$16 million, a record sale price for an NHL team at the time.[9] On May 21, 1980, Skalbania announced that the team would move to Calgary.[10] He chose to retain the Flames name, feeling it would be a good fit for an oil town like Calgary, while the flaming "A" logo was replaced by a flaming "C". Skalbania sold his interest in 1981, and the Flames have been locally owned since.
