- typical personal cassette player
The "personal" stereo system has been one of the
major and obvious steps in the evolution of audio. But one
of the main men behind the evolution Shu Ueyama of Sony, states
that this invention was purely accidental. The first personal
stereo design occured at Sony in 1979, when the tape recorder
division were pressed into making a new device quicker to
boost slowing profits in it's sector. Their invention was
a small cassette player capable with stereo playback that
also included a pair of headphones. Sony soon released how
it would sell, and Sony founder Akio Morita was soon eager
to market it. By March 24, 1979 the design was completed and
the marketing campaign started. Therefore the personal stereo
was born. Sony soon named the device the 'walkman', and it
was always the best selling personal cassette player. Nowadays
the cassette player is slowly being eliminated by new technologies
such as CD and Mp3.
