Mr. Morita prided himself in particular on the Walkman, the portable stereo cassette player with headphones. Actually, according to the company's official corporate history, it was Mr. Ibuka who came up with the idea for the portable product. But Mr. Morita pressed hard for the project, overcoming resistance within Sony to a tape player that, in its early versions, could not record. Mr. Morita, despite initial reservations about the awkward name, eventually ordered all Sony subsidiaries around the world to begin using it.
