Before the Walkman, music in public was a shared thing — a radio, a boombox, a record at home. When Sony released the TPS-L2 in 1979, it invented something genuinely new: a private soundtrack you could carry, a way to wrap yourself in your own music while walking through the world. Sony’s own marketers predicted it would sell a few thousand a month; it sold tens of thousands in weeks, and somewhere around 200 million cassette Walkmans followed over three decades.
It was killed by the very idea it had created, taken further. The Discman, the MiniDisc, and finally the MP3 player and the iPod offered the same private soundtrack without the tape, the rewinding, or the limit of an album per side. Sony ended Japanese production of the cassette Walkman in 2010. The device is gone, but the habit it taught — the public solitude of headphones — is now nearly universal.
Worth remembering
- The original TPS-L2 had two headphone jacks and a 'hot line' button, so two people could share the music and talk over it — Sony assumed listening alone would feel rude.
- 'Walkman' entered the Oxford English Dictionary in 1986 and became the generic word for any personal stereo.
