The roots of today’s NBA date all the way back to 1946, when it was known as the Basketball Association of America. Since then there have been several mergers including the absorption of the National Basketball League in 1949 and merger with the American Basketball Association in 1976 and a vast number of teams that have played under the umbrella of the National Basketball Association.
But there are just three franchises that can proudly state they have been a part of the league since its inception in 1946: the Warriors, New York Knicks and Boston Celtics.
Entering the 2021-22 season, the Knicks have acquired two NBA championships while the Warriors are tied for the third most in the league with six championship titles.
