At the time, many people thought it was foolhardy to build a radio using transistor, but they overcame many obstacles and succeeded in developing Japan's first PNP alloy transistor prototype in 1954. In 1952, when Sony's founder, Masaru Ibuka learned that Western Electric was going to release its transistor patents to the public for a fee, he decided to take on the challenge of developing a radio using Sony's own transistors.
