The Slam Dunk Contest is an annual National Basketball Association (NBA) competition held during the NBA All-Star Weekend. The contest was inaugurated by the American Basketball Association (ABA) at its All-Star Game in 1976 in Denver, the same year the slam dunk was legalized in the NCAA. As a result of the the ABA-NBA merger later that year there would not be another slam dunk contest at the professional level until 1984. The contest currently uses fan voting, via text-messaging, to determine the winner of the final round. The current sponsor of the event is Sprite, an American soft-drink.
The very first slam dunk contest was won by Julius Erving at the 1976 ABA All-Star Game. The current champion of the NBA Dunk Contest is Nate Robinson of the New York Knicks, who has won for two consecutive years and is the only player to win it more than twice.
