L.P. recordsIn 1931, very early versions of 33 rpm long-playing records were first demonstrated at the Savoy Plaza Hotel in New York by RCA (Radio Corporation of America). The record players were so expensive that the product flopped. The first plastic LP records as we know them, did not come out until 1948, when RCA rival, Columbia, began mass production of the LP. |
