The Sony Walkman first went on sale in which country?

Walkman is a brand of portable 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 cofounder Masaru Ibuka, 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.

The metal-cased blue-and-silver Walkman TPS-L2, the world's first low-cost portable stereo, went on sale in Japan on July 1, 1979, and was sold for around ¥39,433.58 (or $150.00), or ¥57,109.02 (or $498.66) adjusted for inflation. Though Sony predicted it would sell about 5,000 units a month, it sold more than 50,000 in the first two months. Sony introduced the Walkman in the US as the Soundabout and the UK as the Stowaway; as developing new, copyright-free names in every country was expensive, Sony settled on Walkman, a play on Pressman. The TPS-L2 was introduced in the U.S. in June 1980.
