 | | It is dated at 1894, with some evidence of earlier similar attempts, although no footage or recordings have come to light. |
 | | Within a year, Edison was marketing the kinetophone; essentially a peep-show kinetoscope with a phonograph inside it! |
 | | Devices such as the kinetophone and vitaphone, which employed a gramaphone type disc driven by belts geared up to a projector, were expensive and inreliable (suffering from atmospheric humidity, rotten drives, even rats eating the leather!) If the film broke, as it regularly did, you would never be able to fix the sync! |
