In Manhattan, most surface transportation was eventually operated by the Fifth Avenue Coach Co. and its subsidiaries. Fifth Avenue Coach Co. was formed in 1896, first operating horse drawn omnibuses on Fifth Avenue, later expanding onto other streets which did not have streetcar routes.
Most of the streetcars were operated by New York Railways (NYRys), which in 1925 was acquired by Fifth Avenue Coach Co. as a subsidiary. Also in 1925, Fifth Avenue Coach Co. formed another subsidiary, New York City Omnibus Co. (NYCO), to operate the bus routes which would replace the streetcars. That company actually began operating buses in 1936, the year when all of the New York Railways streetcar routes were converted.
A few New York Railways streetcar routes were converted in earlier years, with buses operated independently.
In addition, the Third Avenue Railway Co. continued to operate streetcars in Manhattan, which were subsequently replaced by operated by subsidiary Surface Transportation Corp. In 1956, the Third Avenue Railway Co. merged with the Fifth Avenue Coach Co. And in 1962, the city took over the Fifth Avenue Coach Co. operations with the city. A separate entity, the Manhattan & Bronx Surface Transit Operating Authority (MaBSTOA), was formed to operate the routes. This was to isolate any legal complications of the takeover from the main New York City Transit Authority (NYCTA). MaBSTOA continues to exist as a separate operating entity, although perceived by the public as part of the same system as NYCTA.
A few smaller companies also operated some streetcar and bus routes independently. These routes eventually became the only Manhattan routes actually operated by NYCTA.
The Hamilton Bus Company began operating the Houston St/Avenue C route in 1929, was sold to the Triangle Bus Co, in 1935, and to New York City Omnibus Co. in 1940.
Beginning in 1919, several bus routes began operation, operated by independent owner operators granted permits by the New York City Department of Plant & Structures (DP&S). DP&S routes were assigned numbers in the order in which they were introduced, in all five boroughs. Some routes did not survive long and are not listed. In 1933 these routes were assumed by Green Bus Lines, and received "M" route numbers.

In 1935, the Madison/Chambers and the 49/50 St Crosstown route franchises were awarded to the Comprehensive Omnibus Co. And in 1936, the remaining Green Bus Lines route franchises in Manhattan were awarded to the New York City Omnibus Co. At that same time, Green Bus Lines was permitted to expand significantly in Queens.
The East Side Omnibus Co. operated buses originally to replace the streetcars operated by the Second Avenue Railroad. In 1948, the East Side Omnibus Co. and the Comprehensive Omnibus Co. were acquired by the city.
After the Dry Dock East Broadway & Battery Railroad failed in 1932, the Avenue B & East Broadway Transit Co. began operating buses over that route. That remained the last independent bus operation in Manhattan, until the NYCTA took over the route in 1980.
Where no streetcar company is listed, route started new as a bus route.
Where no recent route number is indicated, route has been discontinued.
Around 1989, the crosstown routes were given new numbers corresponding to the numbered streets.
Effective 1/8/2017, the M5 route was split at Midtown Manhattan, with the south segment becoming route M55.
