During the "golden age" of Hollywood, The Big Eight referred to the eight major Hollywood movie studios. Since then, the number of major studios has fluctuated with bankruptcies -- RKO Radio Pictures, mergers -- United Artists and the 'promotion' of what was previously a 'minor' studio, e.g. The Walt Disney Company. The demotion of MGM leaves a current Big Six.
Big Eight is sometimes used to refer to the eight corporations that own the Big Ten, the ten major Hollywood movie studios.
