Dennis Murphy (sports entrepreneur)

In 2010, Murphy was part of the initial group of individuals elected to the World Hockey Association Hall of Fame.

Roller Hockey International (1992–1999) was Murphy's most recent professional sports league. In his autobiography, |MURPH, The Sports Entrepreneur Man and His Leagues: ABA, WHA, WTT, RHI, IFL, GHA, and Bobby Sox Softball," self-published in 2002, Murphy wrote that one day in 1991, he saw some kids playing roller hockey, and he told his brother John what he had seen:

In 1988, Murphy moved on to try to create the International Basketball Association. As in all of his leagues, there were tweaks made to the traditional game. The IBA, which began with 12 teams in May, 1988, was limited to players 6′4″ and under.

As in most of Murphy's leagues, franchises appeared and disappeared like figures in Whack-a-Mole. The league finally disappeared in 1979, but not before four teams joined the NHL – the Edmonton Oilers, New England Whalers, Quebec Nordiques, and Winnipeg Jets. On May 20, 1979, the Jets won their third AVCO World Trophy by defeating the Oilers in the final WHA game.

The ABA folded after its 1976 season, but Murphy had been working on two other professional sports leagues, the World Hockey Association and World Team Tennis. The WHA debuted in 1972 and ran through 1979 and was the National Hockey League's first major competitor since the Western Hockey League in 1926. The WHA gave the more established league fits by cannibalizing NHL rosters, signing players under 20-years old directly from Major Junior (Wayne Gretzky), by placing teams in major cities that didn't host NHL teams, and by successfully challenging the reserve clause that bound players to their teams. This victory gave NHL players the opportunity to split to the upstart league, and Bobby Hull took full advantage. Hull signed a record 10-year, $2.75 million contract, and 66 NHL players followed Hull's lead in the NHL's first year.

Murphy co-founded World Team Tennis(WTT) in 1973 with Larry King, Fred Barman and Jordan Kaiser, and league play began in 1974 with 16 teams, a four-color tennis court, and teams made up of two men and two women. This made WTT the first professional sports league to give equal weight to each man and woman competing for their teams. Elton John wrote the theme song Philadelphia Freedom for his good friend Billie Jean King. The first league ended play in 1978.

From 1973 and 1979, the Dennis A. Murphy Trophy was presented to the best defenseman of the World Hockey Association.

Stung by this defeat, Murphy set his sights on pro basketball. In the 1960s, the National Basketball Association consisted of 12 teams, and had successfully fought off a challenge by Abe Saperstein's (Harlem Globetrotters) America Basketball League. Teaming up with attorney Gary Davidson, Murphy worked on creating a league, the American Basketball Association, that eventually merged several teams into the NBA. The ABA became famous for its three-point shot, slam dunk and red, white and blue basketball... not to mention players like "Dr. J." Julius Erving, Rick Barry, George Gervin, Connie Hawkins, and many others. In 1967, ABA Commissioner George Mikan presided over the league's 11 teams in the inaugural season: the Pittsburgh Pipers, Minnesota Muskies, Indiana Pacers, Kentucky Colonels, New Jersey Americans, New Orleans Buccaneers, Dallas Chaparrals, Denver Rockets, Houston Mavericks, Anaheim Amigos and Oakland Oaks.

Ralph Backstrom, who had won six Stanley Cup Championships with the NHL's Montreal Canadiens, was hired as the new league's commissioner. Murphy had known Backstrom from his days as a player in the WHA following his NHL career. Then living in Denver, Colorado, Backstrom was the National Hockey League's Rookie of the Year for the Canadiens in 1959. Backstrom oversaw the league's rules and style of play.

In 1958, Murphy was elected and began to serve as a one-term mayor of Buena Park, California; but his career path changed when he met Jim Hardy, a close friend of future Oakland Raiders owner Al Davis. Hardy had also attended the University of Southern California with Murphy, and he asked for his fellow alum's help in pursuing a team for Anaheim's new stadium (set to house Gene Autry’s California Angels of Major League Baseball) for the new American Football League. Anaheim's proposed team was quashed in 1960 when Al Davis, as one of the conditions of accepting a merger between the National Football League and the AFL, agreed that no additional team would be permitted in the Los Angeles market alongside the L.A. Rams.

Dennis Arthur Murphy (September 4, 1926 – July 15, 2021) was an American sports entrepreneur who helped co-found the American Basketball Association (1967–1976) (with Gary Davidson), the World Hockey Association (1972–1979), the original World Team Tennis (1973–1978) with Larry King, Roller Hockey International (1992–1999), and several other trend-setting amateur and professional sports concepts and events. Each of his innovations exhibited ground-breaking marketing and promotional tactics, new rules, and a style of play that forced the evolution of the entrenched incumbent. Among the many visionary rules and promotional concepts introduced by Murphy include the 3-point shot (ABA), the Slam-Dunk Contest (ABA), team cheerleaders (ABA), the first $1 million contract (WHA), and he paved the path for the ever-growing wave of European and Russian hockey players that now play in North America.

According to his 2013 autobiography, "Murph: The Sports Entrepreneur Man," Murphy was born in Shanghai, China, on 4 September 1926, to a father who worked for Standard Oil and a housewife mother, Murphy and his family moved back to the United States a year before the Japanese attacked Pearl Harbor in 1941. A staff sergeant in World War II, Murphy joined the reserves after the war and came out of the Korean War as a captain. Murphy attended the University of Southern California on the GI Bill majoring in economics. He was a one-term mayor of Buena Park in Orange County, California (April 15, 1958 to July 17, 1959), before becoming a marketing executive for one of California's biggest civil engineering firms, Voorheis, Trindle, and Nelson.
