July 1: Sony Walkman went on sale


“Don’t you think a stereo cassette player that you can listen to while walking around is a good idea?”—proved to be one of the great understatements in business history.

After a breakneck development phase of only four months, Sony engineers had a reliable product ready for market at 30,000 Yen (approximately US$150 in 1979 dollars) and available before the start of summer vacation for Japanese students—both critical targets established at the outset of development. The initial production run of 30,000 units looked to be too ambitious after one month of lackluster sales (only 3,000 were sold in July 1979). But after an innovative consumer-marketing campaign in which Sony representatives simply approached pedestrians on the streets of Tokyo and gave them a chance to listen to the Walkman, the product took off, selling out available stocks before the end of August and signaling the beginning of one of Sony’s greatest success stories.
