Walkman

Walkman is a very popular Sony brand used to market its portable audio players, and is synonymously used to refer to the original Walkman portable personal stereo player and as a generic term for similar devices from other manufacturers. The original Walkman introduced a change in music listening habits, allowing people to carry their own choice of music with them. In March 2007, Sony extended the Video Walkman brand by launching its first digital, flash-based video Walkman, the NW-A800.

The original Walkman was released in 1979 as the Walkman in Japan and Soundabout abroad. The device was created by audio division engineer Nobutoshi Kihara for Sony co-chairman Morita, who wanted to be able to listen to operas during his frequent transpacific plane trips. Morita hated the Walkman and asked it to be changed, but relented after being told by junior executives that a promotion campaign had already begun using the 'Walkman' name and would be too expensive to change.

The names "Walkman", "Pressman", "Watchman", "Scoopman", "Discman", and "Talkman" are trademarks of Sony, and have been applied to a wide range of portable entertainment devices manufactured by the company. Sony continues to use the "Walkman" brand name for most of their portable audio devices, after the "Discman" name for CD players was dropped in the late 1990s. According to Sony, the plural form is "Walkman Personal Stereos", rather than "Walkmans" or "Walkmen" (presumably to preserve their trademark on "Walkman").
