Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound.Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can ...

Thomas Edison's work on two other innovations, the telegraph and the telephone, led to the development of the phonograph. Edison was working on a machine in 1877 that would transcribe telegraphic signals onto paper tape, which could then be transferred over the telegraph again and again. The phonograph was both in a cylinder and a disc form.
