In 1877 Thomas Edison was experimenting with a new telegraph devise when he accidentally runs indented tin foil under a stylus. The resulting speech like noise encourages him to develop an instrument that can both record and reproduce sound. By the end of the year Edison had produced the first working phonograph able to 'store' and playback sound.

Before Edison, others including Charles Cros had the idea, but were unable to fund them.

1887 Edison updates the phonograph by using a solid wax cylinder and a battery-driven motor as opposed the original hand crank,giving a constant pitch.

1888 Emile Berliner invents the gramophone which used a 7 inch disc which was manually turned at around 30

New York CBS called a press conference to announce the introduction of the LP or long player. 12 inches wide, turning at 33 1/3 or 45 rpm the vinyl disc seemed a lot cheaper and easier to mass produce.It was a record that c
