Latin `for all' vehicle that carries fare-paying passengers on a fixed route, with frequent stops where passengers can get on and off. An omnibus appeared briefly on the streets of Paris in the 1660s, when the mathematician Blaise Pascal introduced the first horse-drawn vehicles for public use. But a successful service, again in Paris, was not established until 1827. Two years later George Shillibeer introduced a horse-drawn bus in London. Many bus companies sprang up in the UK, the most successful being the London General Omnibus Company, which operated from 1856 until 1911, by which time petrol-driven buses had taken over. Following deregulation in the 1980s, private bus operators in Britain were allowed outside London to set up fare-paying routes. Gasoline-engine buses came into general use by the 1910s and provide intracity and nationwide service through both public and private companies.
