The birth of the Sony Walkman

The portable cassette player that brought music-on-the-move to millions of people was launched in 1979. By the time production of the Walkman came to an end 30 years later, Sony had sold more than 220 million machines worldwide. In 2019 Farhana Haider spoke to Tim Jarman, who purchased one of the original blue-and-silver Walkmans. This programme is a rebroadcast. (Photo by YOSHIKAZU TSUNO/Gamma-Rapho via Getty Images)
