Phonograph cylinders (also referred to as Edison cylinders after their creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound. Known simply as records in their heyday (c. 1896–1916), a name since passed to their disc-shaped successors, these hollow cylindrical objects have an audio recording engraved on the outside surface which can be reproduced when they are played on a mechanical cylinder phonograph.
