In 1994, the MTA spent $3 million rebranding its five subsidiaries with simpler names to convey that the different agencies were part of one agency. Surveys found that a majority of riders did not know that the MTA owned the Long Island Rail Road or the Metro-North Railroad. As part of the changes, the Triborough Bridge and Tunnel Authority was renamed MTA Bridges and Tunnels; Staten Island Rapid Transit was renamed MTA Staten Island Railway; Metropolitan Suburban Bus Authority was renamed MTA Long Island Bus. In addition, New York City Transit Authority was renamed MTA New York City Transit to seem less authoritarian, Metro–North Commuter Railroad was renamed MTA Metro-North Railroad to recognize the increase in non-commuter ridership. The MTA logo was changed from a two-toned "M" logo to a blue circle with the MTA initials written in perspective like they were rushing by like a train. The large "M" logos on trains and buses were replaced with decals that state MTA New York City Bus, MTA New York City Subway or MTA Staten Island Railway, eliminating inconsistencies in signage. Today, the older "M" logos survive on existing cube-shaped lamps on station lampposts dating to the 1980s, though such lamps have been updated with more modern spherical lamps over time.
