MGM entered the music industry by purchasing the "Big Three" starting with Miller Music Publishing Co. in 1934 then Robbins Music Corporation. In 1935, MGM acquired a controlling interest in the capital stock of Leo Feist, Inc., the last of the "Big Three". During the first musical craze of 1928–1930, a custom MGM label was created by Columbia using tunes from MGM productions that were recorded by Columbia. These records were sold only at Loew's theaters. (Columbia also created a label called Publix for Paramount music and sold only at Paramount Theaters.)
