History
The Metro Bus brand dates back to the 1993 founding of Metro, but many of the routes in the system are little changed from the bus routes of the prior Southern California Rapid Transit District (RTD) or the streetcar routes operated by the Pacific Electric Red Cars or the Los Angeles Railway Yellow Cars.

Starting in 2003, Metro operated its bus network under three different brands: orange Metro Local buses for traditional routes, red Metro Rapid buses for limited stop routes, and blue Metro Express buses for minimal stop services along the region's extensive freeway network. The separate brands were retired in 2020 as part of Metro's NextGen Bus Plan, a major restructuring of the agencies routes, with most of the Metro Rapid routes retired in favor of more frequent service on the former Metro Local routes, which will now make fewer stops.
