Updated: Wikipedia source
Sony Group Corporation, commonly referred to as Sony, is a Japanese multinational conglomerate headquartered at Sony City in Minato, Tokyo, Japan. The Sony Group encompasses various businesses, including electronics (Sony Corporation), imaging and sensing (Sony Semiconductor Solutions), film (Sony Pictures Entertainment), music (Sony Music Group and Sony Music Entertainment Japan), video games (Sony Interactive Entertainment), and others. Sony was founded in 1946 as initially Tokyo Tsushin Kogyo K.K. by Masaru Ibuka and Akio Morita. In 1958, the company adopted the name Sony Corporation. Initially an electronics firm, it gained early recognition for products such as the TR-55 transistor radio and the CV-2000 home video tape recorder, contributing significantly to Japan's post-war economic recovery. After Ibuka's retirement in the 1970s, Morita served as chairman until 1994, overseeing Sony's rise as a global brand recognized for innovation in consumer electronics. Landmark products included the Trinitron color television, the Walkman portable audio player, and the co-development of the compact disc. Expanding beyond electronics, Sony acquired Columbia Records in 1988 and Columbia Pictures in 1989, while also entering the home video game console market with the launch of the PlayStation in 1994. In Japan, the company further diversified by establishing a financial services division, that would be turned into a separate company in September 2025, with the group maintaining 20% of the shares. In 2021, the company was renamed Sony Group Corporation as it transitioned into a holding company structure, with its electronics business continuing under the name Sony Corporation. As of 2020, Sony holds a 55% share of the global image sensor market, making it the largest image sensor manufacturer, the second largest camera manufacturer, a semiconductor sales leader, and the world's third-largest television manufacturer by sales. Although Sony is not part of a traditional keiretsu, it has historical ties to the Sumitomo Mitsui Financial Group, dating back to the 1950s when it relied exclusively on Mitsui Bank for financing. Sony is publicly traded on the Tokyo Stock Exchange (a component of the Nikkei 225 and TOPIX Core30 indices) and also maintains American depositary receipts on the New York Stock Exchange, where it has been listed since 1961. As of 2021, it ranked 88th on the Fortune Global 500 and 57th on the 2023 Forbes Global 2000 list.
