【How-to】When was the walkman invented

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, and was sold for around ¥33,000 (or $150.00). Though Sony predicted it would sell about 5,000 units a month, it sold more than 30,000 in the first two months.
