Walkman

Walkman is a Sony brand tradename originally used for portable audio cassette players in the late 1970s. In the 2010s, it was used to market Sony's portable audio and video players as well as a line of former Sony Ericsson mobile phones. The original Walkman actually introduced a change in music listening habits by allowing people to carry recorded music with them and listen to music through lightweight headphones. Owners of the Walkman were able to take back their "lost" time, commuting for example, and turn it into a pleasurable experience, or add a soundtrack to their urban surroundings. It was the privatization and personalization offered by the Walkman that lead to its success.

The prototype was built in 1978 by audio-division engineer Nobutoshi Kihara for Sony co-founder Masaru Ibuka. Ibuka wanted to be able to listen to operas during his frequent trans-Pacific plane trips, and presented the idea to Kihara. The original idea for a portable stereo is credited to Brazilian-German inventor Andreas Pavel. The first Walkman was marketed in 1979 in Japan, using the name Walkman. From 1980, it was known as the Soundabout in many other countries including the US, Freestyle in Sweden and was called the Stowaway in the UK. Advertising, despite all the foreign languages, still attracted thousands of buyers in the US specifically. Sony President and co-founder Akio Morita hated the name "Walkman" and asked that it be changed, but relented after being told by junior executives that a promotion campaign had already begun using the brand name and that it would be too expensive to change.
