THIS DAY IN HISTORY JULY 01 The transistor radio was a technological marvel that put music literally into consumers’ hands in the mid-1950s. It was cheap, it was reliable and it was portable, but it could never even approximate the sound quality of a record being played on a home stereo. It was, however, the only technology available to on-the-go music lovers until the Sony Corporation sparked a revolution in personal electronics with the introduction of the first personal stereo cassette player. A device as astonishing on first encounter as the cellular phone or digital camera would later be, the Sony Walkman went on sale for the very first time on July 1, 1979. The Sony Walkman didn’t represent a breakthrough in technology so much as it did a breakthrough in imagination. Every element of the Walkman was already in production or testing as part of some other device when Sony’s legendary chairman, Masaru Ibuka, made a special request in early 1979. Ibuka was a music lover who traveled frequently, and he was already in the habit of carrying one of his company’s “portable” stereo tape recorders with him on international flights. But the Sony TC-D5 was a heavy device that was in no way portable by modern standards, so Ibuka asked his then-deputy Norio Ohga if he could cobble together something better. Working with the company’s existing Pressman product—a portable, monaural tape recorder that was popular with journalists—Ohga had a playback-only stereo device rigged up in time for Ibuka’s next trans-Pacific flight. Even though this proto-Walkman required large, earmuff-like headphones and custom-made batteries (which, of course, ran out on Ibuka midway through his flight), it impressed the Sony chairman tremendously with its sound quality and portability. ** Edited by PhotoHokieNC at 7/1/2022, 7:47:38 AM
