From Betamax to Blu-ray, Sony has had its share of highlights and low points over its more than 50 years. Here are some of the most memorable.
Sony first established itself as an international player in the consumer electronics industry with its innovative transistor radio technology and marketing prowess. Though U.S.-based Regency Electronics produced the original transistor radio, Sony was the first to recognize the gadget's consumer appeal and to successfully market a model built entirely from its own components.
Sony later refined its original TR-55 -- which debuted in 1955 -- into the "pocket-sized" TR-63 and TR-610 models of 1968, which quickly turned into global sensations and helped Sony gain a crucial foothold in the European and American markets. Sony sold 500,000 TR-63 units worldwide, an accomplishment some attribute to its clever marketing tactics: Sony salesmen tried to convince customers that the TR-63 transistor radio was truly pocket-sized by wearing shirts with larger-than-average pockets.
