It's been suggested that based on some of the hyperbole that the game was invented by Larry Bird and Magic Johnson, both rookies in the 1979-80 NBA season. But the league began in the late 1940s and was dominated by the then Minneapolis Lakers, winners of five league championships over a six-year span. The Lakers team included George Mikan, the game's first dominant big man. The league instituted a shot clock in the 1954-55 season. No longer would there be defensive struggles like the Fort Wayne Pistons 19-18 defeat of the Lakers in a 1950 game. The league added the three-point shot in the 1979-80 season, although it had been used in the American Basketball Association. The ABA had a nine-year life before four of its surviving franchises — the Denver Nuggets, Indiana Pacers, New York Nets, and San Antonio Spurs — merged into the NBA in the 1976-77 season. The first 3-point champion was Fred Brown of the Seattle SuperSonics. The league's most dominant team for a decade was the Boston Celtics who won no less than nine championships during the 1960s. The NBA's greatest team for a single regular season was the Chicago Bulls, who went 72-10 during the 1995-96 season en route to the first of three straight league championships. That was Michael Jordan's first complete season after a brief retirement from the game during which he pursued a baseball career. He didn't play basketball during the 1993-94 season and played only 17 regular-season games at the end of 1994-95. In the 1992 Olympics the U.S. fielded its first team made up mostly pros, the dream team. The U.S. team won the gold medal at Barcelona. The team included three members of the 1984 team that won the gold medal in Los Angeles as amateurs — Patrick Ewing, Michael Jordan, and Chris Mullin. Among others on the dream team roster were Charles Barkley, Larry Bird, Magic Johnson, Karl Malone, and John Stockton. The only amateur on the roster was Christian Laettner, who would begin his NBA career that autumn.
