In Brooklyn, all streetcars and buses were eventually operated by Brooklyn Manhattan Transit, which in 1923 succeeded the Brooklyn Rapid Transit Co. The same company also operated subway trains. In 1940, Brooklyn Manhattan Transit was acquired by the city.
Some bus routes were originally operated by independent operators, prior to being operated by Brooklyn Manhattan Transit. Original operating company names are indicated. By the early 1930's, all bus routes were operated by Brooklyn Manhattan Transit.
All trolleybus routes were at one time streetcar routes.
In 1961, route B72 became route Q72 in Queens, operated by Triboro Coach Co. until 2006, when taken over by MTA Bus.
Around 1989, several former Brooklyn routes which had operated through into Queens, were redesignated as Queens routes, with "Q" route numbers.
Where no recent route number is indicated, route has been discontinued.

Not listed, and until 2008 not shown on NYCTA bus maps, are express bus routes into Manhattan, previously operated by private carriers and subsidized by the New York City Department of Transportation. These routes have numbers beginning with "BM", reflecting both boroughs. In 2004, the Metropolitan Transportation Authority (MTA) formed a new subsidiary, MTA Bus, to take over the remaining private bus operations in New York City. And in December 2005, MTA Bus took over all routes which had been operated by the Command Bus Co.The Command Bus Co. had replaced the Pioneer Bus Co. in 1979. The Pioneer Bus Co. was originally a school bus operator, which in 1960 began operating local bus route B100 in Brooklyn. And in 1972 began operating express bus service between Brooklyn and Manhattan. And route B103 was added later.
