<P> The NBA originated in 1946 with 11 teams, and through a sequence of team expansions, reductions, and relocations currently consists of 30 teams . The United States is home to 29 teams and one is located in Canada . </P> <P> The current league organization divides thirty teams into two conferences of three divisions with five teams each . The current divisional alignment was introduced in the 2004--05 season . Reflecting the population distribution of the United States and Canada as a whole, most teams are in the eastern half of the country: thirteen teams are in the Eastern Time Zone, nine in the Central, three in the Mountain, and five in the Pacific . </P> <Table> <Tr> <Th> Division </Th> <Th> Team </Th> <Th> City / State </Th> <Th> Arena </Th> <Th> Capacity </Th> <Th> </Th> <Th> Founded </Th> <Th> Joined </Th> <Th> Head coach </Th> </Tr> <Tr> <Th_colspan="9"> Eastern Conference </Th> </Tr> <Tr> <Th> Atlantic </Th> <Td> Boston Celtics </Td> <Td> Boston, Massachusetts </Td> <Td> TD Garden </Td> <Td> 18,624 </Td> <Td> 42 ° 21 ′ 59" N 71 ° 03 ′ 44" W ﻿ / ﻿ 42.366303 ° N 71.062228 ° W ﻿ / 42.366303;
