Sony Corporation, a Japanese multinational conglomerate, was founded in 1946 by Masaru Ibuka and Akio Morita. Originally named Tokyo Tsushin Kogyo (Tokyo Telecommunications Engineering Corporation), the company adopted the name Sony in 1958. Sony has played a pivotal role in the development of consumer electronics and entertainment technologies, introducing iconic products such as the Walkman and the PlayStation gaming console. While specific details about the registration of their first trademark are not readily available in my training data, Sony is recognized for its simple yet powerful wordmark (first registered as a trademark in 1956) and distinctive logo, symbolizing the innovative and high-quality products for which the company is renowned.
