The Sony Walkman turns 40 on July 1. The portable cassette stereo revolutionized how we consume music on the go, quickly seeped into pop-culture, and meaningfully preceded Jony Ive's iPod design.
The Walkman was inspired by Sony's cofounder Masaru Ibuka, who wanted a portable device he could use to listen to music on long flights.
Sony released the TPS-L2 Walkman in July 1979 in Japan. The device made it stateside by Christmas 1979, and by the next summer, The New York Times was calling it "the newest status symbol around town" in an article recently uncovered by Mentalfloss.
