The Walkman at 40 Years Old: How Sony Changed Music Forever

The Sony Walkman is Now Tito Years Old.

Before 1979, people listened to music on the radio, or on vinyl records at home. At the time, compact cassette tapes were also pretty much the standard. Compact cassettes, or simply cassettes, were invented by Dutch company Philips in 1963 with the original purpose of recording audio material, ideal for journalists and secretaries. They sold “blank” or unrecorded cassettes for the first year, but they realized that there was huge untapped market for cassettes with prerecorded music.

The Birth of the Audiocassette

In 1964, the music cassette was born, which would be known as musicassette, M.C., or audiocassette. For the rest of the decade, audiocassettes started disrupting the music industry, becoming a viable alternative to vinyl. However, issues with sound quality and performance impeded the cassette’s dominance in that decade. It was only during the ‘70s when cassettes saw a significant improvement in both sound quality and performance when it finally became a popular alternative to vinyl records. It would not be until 15 years later, on July 1, 1979, after the audiocassette’s invention when people would be introduced to the Sony Walkman TPS-L2: a portable cassette player that comes with earphones.

The Birth of the Walkman

It seems unbelievable today that people in the ‘70s used to have no idea what headphones or earphones are, things that are ubiquitous today and were popularized by the Walkman.

When Sony co-founder and music lover Masaru Ibuka travelled in the 70’s, he would often find himself towing Sony’s bulky stereo cassette recorder and player, the TC-D5, just to listen to music. Probably tired of hauling the stereo on his business trips, Ibuka tasked Sony’s Executive Deputy President Norio Ohga to scale down the TC-D5’s design and design something that only plays music.


The result was a prototype: a high-quality, compact, and portable cassette player.

Masaru took the product and brought it to Sony chairman Akio Morita. “Try this. Don't you think a stereo cassette player that you can listen to while walking around is a good idea?" Ibuka reportedly said. Apparently, Morita decided it was a good idea, because the next thing Ibuka knew, Sony were coming with names to call the new device.

For the U.S., Sony’s new portable cassette player was initially named Sound-About, while for the UK, they opted for Stowaway. The plan for having different names to suit different countries was probably a leaf taken from car manufacturers, which didn’t pan out well for Sony because it realized that patents and copyrights for each country for a single product were expensive. It eventually came up with the name Walkman, which is a play on Sony’s earlier cassette recorder, the Pressman (which was typically used by pressmen or journalists to record interviews).

The simplicity of the Walkman’s design changed forever the way people listened to music. Although it was not the first product to feature portable audio, it was the first to feature audio privacy by having headphones and no external speakers. People loved it and Ibuka’s idea proved to be a gold mine: Sony predicted the Walkman would sell 5,000 a month. It sold 50,000 in two months, and the rest was history.

The Walkman became so popular that it could have played a role in making people want to exercise more. According to a report by Time Magazine, the number of people who walked for exercise increased by 30 percent between 1987 and 1997, the same period when the Walkman was most popular. It could be that millions wanted an excuse to use the Walkman, so they walked as exercise.

The Walkman and Cassette Culture

The success of the Walkman not only meant the start of the era of portable music, but also of cassette culture: home recording, tape trading, and creating mix tapes.

Cassette culture refers to the various practices associated with the reproduction and redistribution of recorded music using cassette tapes. Although compact cassette tapes had been around quite some time before the Walkman, the latter also helped make the compact cassette the dominant format in recorded audio.

Tape trading was a trend in which people mailed recorded music to each other through the postal system. Such cassettes could contain audio of recorded concerts, radio broadcasts, or personal recordings of music.

A mixtape is a cassette with typically bootlegged compilation of music usually recorded from radio broadcasts. A person had to wait to chance upon a particular song he or she liked to play on the radio, and then record it on the cassette. It would usually take days or weeks to complete a single playlist in a mixtape because of the difficulty of compiling songs. Receiving a mixtape as a present or a gift meant a big deal.

An example of a mixtape is Awesome Mix Vol.1 from Guardians of the Galaxy (2014), a sort of time capsule from the ‘80s that represents Peter Quill’s only remembrance of his life on earth before he was abducted by aliens and became Star Lord.

The Walkman in Its Final Years

Many of us have not picked up or listened to music on a Walkman for decades, but interestingly, Sony only pulled the plug on the cassette Walkman’s production in 2010, according to a report by


In the mid ‘90s, the cassette was gradually eased out as the dominant format for audio, replaced by the compact disc or CD. Sony came out with the Discman, a CD version of the cassette-based Walkman. In the early 2000s, the CD player was also replaced by the MP3 player, which was even more compact.

Today, Sony has rebranded the Walkman as its line of high-fidelity audio players. The Walkman has sold over 220 million units of portable audio players since it launched in 1979. The Walkman remains one of the most beloved icons of pop culture, including its appearances in the Guardians of the Galaxy films.
