A brand of portable media players manufactured by Sony. The original Walkman, released in 1979, was a portable cassette player that allowed people to listen to music of their choice on the move. The first Walkman prototype was built from a modified Sony Pressman, a compact cassette recorder designed for journalists and released in 1977.
The metal-cased blue-and-silver Walkman TPS-L2, the world’s first low-cost personal stereo, went on sale in Japan on July 1, 1979. Though Sony predicted it would sell about 5,000 units a month, it sold more than 30,000 in the first two months. The TPS-L2 was introduced in the US in June 1980.
