Sony Ends Production of Walkman - The Hollywood Reporter 3:24 AM 10/25/2010 by Kimberly Nordyke Move comes a day before the ninth anniversary of the iPod; 200 million units of device were sold over 30-plus years. It's the end of an era: Sony has announced that it plans to stop manufacturing and selling its cassette-based Walkman, according to Gizmodo. Incidentally, the last day of the Walkman's production was Friday, the day before the iPod celebrated its ninth anniversary. The Walkman, which is credited with changing the way people were able to listen to music, was built in 1978 by audio-division engineer Nobutoshi Kihara for Sony co-chairman Akio Morita, who wanted to be able to listen to operas during his frequent trans-Pacific plane trips. The device wasn't an instant hit, but Sony kept marketing the product toward younger consumers, and it eventually caught on, selling 200 million units over 30-plus years. Once CDs hit the marketplace, the Walkman went out of favor by consumers, who first gravitated to Sony's own Discman and other CD-based portable and, later, iPods. When you saw that headline. Did you think; "They were STILL making walkmans?" Or was that just me?
