 | | Recording on disc as opposed to phonograph cylinder had been contemplated and experimented with by such inventors as Charles Cros, Thomas Edison, Chichester Bell, but the first to actually develop usable disc record technology was Emil Berliner, a German working in Washington, D.C, in 1884. |
 | | The first disc recordings for phonographs or gramophones were commercially marketed in 1895, and they gradually overtook the earlier phonograph cylinder as the dominant medium of recorded sound by the 1910s. |
 | | All speeds of records were made in various sizes, mainly 7, 10 and 12 inches diameter; the 7-inch being most common for the 45rpm, the 10-inch for the 78 (and the first few years of 33&1/3 production), and the 12-inch for the 33 from the mid 1950s on. |
