Sony Walkman

The cassette player that invented personal portable music — retired by Sony after four decades

Defunct — The Sony Walkman launched in 1979 and created personal portable music, going on to sell hundreds of millions of units. Sony ended the cassette Walkman line in 2010, and the classic product is now an icon of a bygone physical-media era.

The Sony Walkman was introduced in Japan in 1979 and changed the way people listened to music. For the first time, a portable cassette player with lightweight headphones let anyone carry a personal soundtrack anywhere, and the Walkman became a global sensation almost instantly.

Sony sold the Walkman in many forms over the years, from the original cassette model to CD and MiniDisc players, and later digital audio players that carried the same name. It became one of the most iconic consumer products of the twentieth century, synonymous with portable music.

In 2010, Sony discontinued the cassette-based Walkman, ending the product line that had defined portable audio for a generation. The classic Walkman is now a collector's item and a symbol of the physical-media era.
