The NBA Slam Dunk Contest (officially known as the AT&T Slam Dunk) is an annual National Basketball Association (NBA) competition held during the NBA All-Star Weekend. Sports Illustrated wrote "the dunk contest was the best halftime invention since the bathroom." The contest was conceived of and started by the American Basketball Association (ABA) for its 1976 ABA All-Star Game in Denver. The winner was Julius Erving of the New York Nets. As a result of the ABA–NBA merger later that year, the contest moved to the NBA for the 1976-1977 season. There was not another slam dunk contest at the professional level until 1984. The contest has adopted several formats over the years, including, until 2014, the use of fan voting, via text-messaging, to determine the winner of the final round. The current champion of the Slam Dunk Contest is Mac McClung of the Philadelphia 76ers. History 1976 ABA Slam Dunk Contest The first-ever Slam Dunk Contest was held on January 27, 1976 at McNichols Sports Arena in Denver during halftime of the 1976 ABA All-Star Game. In financial trouble and fighting with the NBA for viewers, the ABA started the slam dunk contest as a gimmick to attract viewers nationwide. In Remember the ABA, Jim Bukata recalled, "We were sitting around the office one day, discussing things that would draw more people, and it just came to us…It was Julius [Erving] really giving us the idea that we're the league of the dunkers. So we said, 'Well if that's the case, let's have a contest.' It really was as simple as that. …Three guys talking about what we could do to sell a few more tickets." Bukata was the director of marketing and public relations for the ABA. The other two in the room were the league's finance director Jim Keeler and Carl Scheer, general manager of the Denver Nuggets who were hosting the All-Star game. There was a format each competitor had to follow in which they must attempt five dunks in a row under two minutes, with the clock stopping after each shot to allow the player to plan their next attempt. One required dunk was from a standing position under the basket, and another from a distance of ten feet away from the basket in the foul lane. The next three required dunks were freestyle positions, one coming in from the left side of the basket,
