The launch of the Walkman

Available for over a year

The portable cassette player that brought us music on the move was launched in July 1979. By the time production of the Walkman came to an end thirty years later, Sony had sold more than 220 million machines worldwide. Farhana Haider has been hearing from Tim Jarman, who purchased one of the original blue-and-silver Walkmans. (Photo by YOSHIKAZU TSUNO/Gamma-Rapho via Getty Images)
