In 1877 Thomas Edison invented a little thing called the Phonograph (which means sound writer). In 1887, Emile Berliner developed a little thing called the Gramophone, which replaced Edison's cylinder with flat discs. Berliner joined Eldrige Johnson to form the Victor Talking Machine Company that would later become know to millions as RCA Victor. Early players required large horns to amplify the sound, later becoming housed in the cabinet below the actual player.
In 1927 the first Jukebox was manufactured and brought music to restruants and nightclubs. 1947 Peter Goldmark while listening to Brahms' Second Piano Concerto hated the interuptions from having to turn over the record and the sound defects he detected created the LP (long playing) record which could play for 23 minutes and were larger that the 78rpm records of the World WarII era. William Paley, of CBS radio and records, realized he was taking a big risk introducing LP records when he knew most people didn't own the proper record player to play them. He contacted RCA exec. David Sarnoff to convince him to partner up and make a record player to play the LP records but Sarnoff refused. In 1948 Sarnoff introduced his own 7 inch, 45rpm record, they were perfect for jukeboxes. Eventually Toscanini convinced Sarnoff to manufacture LP records to include33 1/3 spd on RCA record players and in turn CBS would use 45s for it's popular songs. Eventually a record player was made that could play all 3 sizes of records.
1950s saw the introduction of rocknroll and the developement by London Records of High Fedelity. Quadraphonic(4track) and 8 track were almost destined to become the standard of the 1970's but that pesky cassette tape was holding up pretty good. 1979 Sony introduced us to the walkman as a personal stereo.
Today the CD is transforming music in to digital code on a 4.7 inch disc read by lasers. In 2000 CD players that included a CD recorder and computers with a CD-RW drive meant consumers could burn data such as music to a blank CD, play it and then re-record on the same disc.
