Sony

From the Walkman to the ES series — relentless innovation

History

Sony Corporation was founded in Tokyo, Japan in 1946 by Masaru Ibuka and Akio Morita as the Tokyo Tsushin Kogyo Kabushiki Kaisha (Tokyo Telecommunications Engineering Corporation). The company name "Sony" was chosen in 1958 as a mix of the Latin word "sonus" (meaning sound) and the English slang word "sonny"—suggesting smart, presentable young men. Sony's early success came with Japan's first tape recorder, the G-Type (1950). The company then developed the transistor radio (1955), bringing portable music to the masses and establishing Japan as an electronics powerhouse. The 1960s saw Sony enter the hi-fi market with innovative products including the world's first all-transistor television (1959) and the TC-357 tape deck. The company introduced the Compact Cassette (developed by Philips) to Japan and began producing high-quality cassette decks. The 1970s marked Sony's golden era in audio. The company released legendary turntables including the PS-X6, PS-X75, and the professional PS-8750. The STR-7065 receiver became a classic, and the TA-1120 integrated amplifier established Sony's reputation for quality amplification. The 1980s brought the Walkman (1979), revolutionizing personal audio. Sony's ES (Elevated Standard) series raised the bar for consumer audio with components like the TA-E77 preamp and TA-N77 power amp. The company also led the CD revolution with the CDP-101, the world's first commercial CD player (1982). In the 1990s, Sony continued innovating with digital formats including MiniDisc and SACD. The company remains a major force in audio, though consumer hi-fi now represents a smaller portion of its diverse electronics portfolio.
