Before the Walkman, music was a shared thing.
You heard it through a room — a speaker, a crowd, a car radio everyone agreed on.
Sony TPS-L2 shipped July 1, 1979.
ÂĄ33,000 in Tokyo. Two headphone jacks.
No record button. That was the point.

Card 03 — Era
Tokyo, 1980.
For the first time, the soundtrack was yours alone.
Masaru Ibuka, Sony's co-founder, wanted something to listen to on long-haul flights.
His engineers had four weeks.
The two headphone jacks were a hedge — Sony executives didn't believe anyone would listen alone.
They were wrong.
Within a year, Sony had sold over a million units.
The category they called "personal stereo" hadn't existed before July 1979.
The MDR-3L2 headphones that came in the box were orange.
People wore them outside. Publicly.
That was new.
What's the first album you remember hearing on headphones, fully alone?
