Walkman
Walkman is a brand of portable media players manufactured by Sony. The original Walkman, released in 1979, was a portable cassette player that changed listening habits by allowing people to listen to music of their choice on the move. It was devised by Sony founders Masaru Ibuka and Akio Morita, who felt Sony's existing portable player was too unwieldy and expensive. A prototype was built from a modified Sony Pressman, a compact tape recorder designed for journalists and released in 1977.
