MP3 player - 1979

The device was roughly the size of a pack of cigarettes, featured a four-button control system, and could hold about three and a half minutes of music. "In a matter of second," the filing read, "a live performance at Carnigie Hall [sic] can be recorded and available in shops all over the world."
