Phonograph Players - After World War I Emile Berliner's phonograph record won over Edison's wax cylinders. Records were recorded in the 78 rpm format until the late 40s, when Columbia introduced  33 rpm record.  This record had better sound, ten times the amount of recording space and smaller grooves. The smaller needle needed to play the 33 rpm record gave a clearer  and wider spectrum of sounds. In early 1949 RCA   introduced the 45 rpm record. The record was much smaller then the 78 rpm, but contained the same amount of recording space, while offering better sound. Portable record players were developed that would play up to ten 45 rpm records on a spindle These phonograph players were ideal for teen parties and dances. By July 1954, most companies promotional records to disc jockeys were in the 45 rpm format.

Record Formats -33 RPM, 45 RPM, and 78 RPM
