Film Booking Offices of America (FBO), also known as FBO Pictures Corporation, was an American film studio of the silent era, a producer and distributor of mostly low-budget films. It was founded in 1920 as Robertson–Cole (U.S.), the American division of a British import–export company formed by the English-born Harry F. Robertson. Robertson-Cole bought the Hallmark Exchanges (formerly the Mutual Exchanges that became known as Exhibitors-Mutual Exchanges) from Frank G. Hall in 1920. Exhibitors-Mutual/Hallmark had distributed Robertson-Cole product, and acquiring the exchanges gave them the right to distribute their own films plus Hall's product, with the exception of Charlie Chaplin reissues which he had the rights to.
