In 1948 Paramount was bought by John Steiner, who revived the label for reissues of important historical recordings and new recordings of jazz and blues. In 1952 Steiner leased reissue rights to a newly formed jazz label, Riverside Records. Riverside reissued 10" and then 12" LPs by many blues singers in the Paramount catalog, as well as jazz by such Chicago-based notables as Jelly Roll Morton, King Oliver's Creole Jazz Band (which included a young Louis Armstrong), Johnny Dodds, Muggsy Spanier, and Meade Lux Lewis. The Riverside label remained active until 1964. The rights to Paramount's back catalog were acquired by George H. Buck in 1970. The use of the name "Paramount Records" was purchased from Buck by Paramount Pictures, a previously unconnected company.
