Radios, Gramophones & Graphophones
Thomas Edison invented the tin-foil phonograph in 1877. The word "phonograph" was Edison's trade name for his device, which played recorded sounds from round cylinders. The sound quality on the phonograph was bad and each recording lasted for one only play. This was followed by the graphophone. The graphophone used wax cylinders which could be played many times, however, each cylinder had to be recorded separately.
