WHA seasons

The 1976–77 WHA season was the fifth season of the World Hockey Association (WHA). Prior to the season, the Toronto Toros moved to Birmingham, Alabama and became the Bulls. The Cleveland Crusaders attempted to move to South Florida but legal problems resulted in them moving to Minnesota to become the new Fighting Saints. They met with little success there and folded after playing 42 games. The remaining 11 teams competed in the league, playing 80 or 81 games in the regular season.

The 1975–76 WHA season was the fourth season of the World Hockey Association. After the Baltimore Blades and Chicago Cougars folded, the league stayed at 14 teams by adding the Cincinnati Stingers and Denver Spurs. In addition, the Vancouver Blazers franchise moved to Calgary and became the Cowboys. Midway through the season, the Spurs moved to Ottawa and became the Civics, though the team folded shortly thereafter when the sale of the franchise fell through. The Minnesota Fighting Saints became the second team to fold mid-season when the franchise was not financially successful, despite having a winning record at the time. Theoretically, fourteen teams would play 80 games each, but only twelve teams finished the season, with cancelled games involving the Civics or Saints being rescheduled on the fly, and four of five Canadian Division teams played 81 games, as a result.

The 1974–75 WHA season was the third season of the World Hockey Association. Fourteen teams each played 78 games.

The 1973–74 WHA season was the second season of the World Hockey Association. Twelve teams each played 78 games. The Philadelphia Blazers relocated to Vancouver, becoming the Vancouver Blazers. They were moved to the Western Division and Chicago moved to the East. The New York Raiders were renamed the New York Golden Blades and then moved to Cherry Hill, New Jersey to become the Jersey Knights after just 24 games. The Ottawa Nationals moved to Toronto and became the Toronto Toros. The Alberta Oilers changed their name to the Edmonton Oilers.

The 1977–78 WHA season was the sixth season of the World Hockey Association (WHA). Eight teams played 80 games each. The Avco World Trophy winner was the Winnipeg Jets.

The 1978–79 WHA season was the seventh and final season of the World Hockey Association (WHA). Prior to the start of the season, the Houston Aeros folded leaving seven teams to start the season. Only six would finish however, as the Indianapolis Racers folded after 25 games on December 15, 1978. The remaining six teams each played 80 games, including one game each per team against a Soviet All-Star squad and the Czechoslovakian National Team, the second consecutive year for this arrangement. The Soviet team won four of their six games and tied another; the Czechoslovak team only won once and tied once against four losses. In addition, because the Racers had folded after playing an odd number of games, the Edmonton Oilers played the Finnish National Team (with future Oiler Jari Kurri) once at home so as to allow each of the six surviving WHA teams to play 80 regular season games. The Oilers won by a score of 8-4, a result which in itself made no difference by the end of the regular season which Edmonton won by an eleven point margin over the Quebec Nordiques.

The 1972–73 WHA season was the first season of the World Hockey Association (WHA). Twelve teams played 78 games each. The league was officially incorporated in June of 1971 by Garry L. Davidson and Dennis A. Murphy and promised to ice twelve teams in various markets around Canada and the United States. The league championship trophy, the Avco World Trophy, was donated by AVCO Financial Services Corporation along with $500,000. The New England Whalers won the first Avco World Trophy.

The World Hockey Association (French: Association mondiale de hockey) was a professional ice hockey major league that operated in North America from 1972 to 1979. It was the first major league to compete with the National Hockey League (NHL) since the collapse of the Western Hockey League in 1926. Although the WHA was not the first league since that time to attempt to challenge the NHL's supremacy, it was by far the most successful in the modern era.
