Founded through the 1964 merger of Tokyo Television Acoustic Company (1953) and Tokyo Electro-Acoustic Company (1956), TEAC Corporation emerged under founder Katsuma Tani's vision in Tokyo. The company revolutionized audio recording with landmark innovations: Japan's first stereo Hi-Fi cassette deck (A-20, 1968), first consumer four-track reel-to-reel Quadraphonic recorders (1969), and pioneering overdubbing capabilities (1972). TEAC equipment shaped cultural history - recording R2-D2's voice for Star Wars (1977), Bruce Springsteen's 'Nebraska' album (1982), and the 1964 Tokyo Olympics' first slow-motion video. Today, TEAC continues producing premium cassette decks (W-1200, AD-850-SE), turntables, amplifiers, and CD players featuring their acclaimed VRDS vibration-free disc mechanism. With $97.2 million revenue and headquarters in Tokyo, TEAC maintains its 70-year legacy of precision audio engineering while adapting to modern digital formats for discerning audiophiles worldwide.
