Founding Story
Masaru Ibuka and Akio Morita founded Tokyo Tsushin Kogyo in a bombed-out Tokyo department store in 1946. An early rice cooker failed, but the company built Japan's first magnetic tape recorder and, after licensing transistor technology from Western Electric, launched the TR-55 transistor radio in 1955. It adopted the name Sony in 1958, listed ADRs in New York in 1961 and later created the Trinitron TV, the Walkman, the CD with Philips, and PlayStation.
Founders
Masaru Ibuka
Masaru Ibuka was an absolutely legendary Japanese electrical engineer, fiercely visionary industrial pioneer, and the profoundly influential technical patriarch fundamentally responsible for inventing the highly revolutionary electronics that built the massive Sony corporate empire. Operating as an incredibly talented engineer in the devastating aftermath of World War II, Ibuka aggressively launched a small radio repair shop in a bombed-out Tokyo department store in 1946. Relentlessly partnering with Akio Morita to formally incorporate the Tokyo Telecommunications Engineering Corporation (later Sony), he fiercely drove the massive internal R&D that resulted in Japan's first magnetic tape recorder and the incredibly massive global commercialization of the transistor radio. His absolutely rigorous technical leadership completely revolutionized global consumer electronics, permanently establishing the absolute historic bedrock for the multi-billion dollar Sony monopoly. Masaru Ibuka was born in 1908.
Akio Morita
Akio Morita co-founded Tokyo Tsushin Kogyo (Sony) in 1946 and served as its chairman and chief executive through much of the company's global expansion phase. He was the architect of Sony's American market strategy, relocating to New York with his family in 1963 to personally oversee the company's US operations and build retail relationships. He championed the decision to brand all Sony products under the Sony name rather than accepting private-label arrangements, a conviction that proved foundational to the company's global brand equity. Morita drove the Walkman project to completion in 1979 over the internal skepticism of engineers who doubted the commercial market for a headphone-only audio device. He orchestrated the acquisitions of CBS Records and Columbia Pictures in the 1980s, arguing that Sony needed to control software content as well as hardware. He suffered a cerebral hemorrhage in 1993 while playing tennis and never fully recovered, dying in October 1999. He was posthumously awarded the Presidential Medal of Freedom by President Clinton in 1999. Akio Morita was born in 1921.

CBS Records
1987Sony acquired CBS Records for $2 billion in January 1988 (deal announced 1987) to secure ownership of a major recorded music catalog and artist roster, embodying co-founder Akio Morita's conviction that Sony needed to control software content to drive hardware demand. CBS Records' Columbia and Epic label roster included Michael Jackson, Bruce Springsteen, and Bob Dylan, among hundreds of other commercially significant artists. The acquisition was part of Sony's explicit strategy to become a vertically integrated entertainment company rather than solely a hardware manufacturer.
Columbia Pictures Entertainment
1989Sony acquired Columbia Pictures Entertainment for $3.4 billion in November 1989, gaining control of Columbia Pictures, TriStar Pictures, and a film library spanning over 2,800 titles.

Sony Company History FAQ
When and where was Sony originally founded, and what was its original name?
Sony was founded on May 7, 1946, in the bombed-out ruins of the Shirokiya department store building in Nihonbashi, Tokyo, Japan. It was originally established as Tokyo Tsushin Kogyo K.K. (Tokyo Telecommunications Engineering Corporation) by engineer Masaru Ibuka and physicist Akio Morita with an initial capital investment of just ¥190,000 and approximately 20 employees.
What was Sony's first commercial product?
Sony's first commercial product was the Type-G tape recorder, launched in 1950. It was the first commercially produced magnetic tape recorder in Japan. Prior to this, the founders attempted to sell an electric rice cooker made of interlocking wooden slats, which proved unsuccessful commercially but taught them invaluable lessons in product development.
How did Sony acquire the transistor technology that sparked its early boom?
In 1953, co-founder Akio Morita traveled to New York and negotiated a patent licensing agreement for transistor technology from Western Electric (the manufacturing arm of AT&T/Bell Labs) for $25,000. While American firms focused on military and industrial applications, Sony applied the transistor to consumer entertainment, releasing the breakthrough TR-55 pocket transistor radio in August 1955.
What is the linguistic origin of the brand name "Sony"?
The name Sony was coined in 1958 by combining two concepts: the Latin word "sonus," meaning sound, and the popular 1950s American slang expression "sonny" or "sonny boy," used to describe bright, spirited young men. Morita and Ibuka sought a distinctive name that was easy to pronounce in any language and did not exist in any dictionary.
What made the Trinitron color television a breakthrough in display technology?
Introduced in 1968, the Trinitron color television utilized a proprietary single-gun cathode ray tube (CRT) with three beams and an aperture grille, rather than the shadow mask design used by conventional televisions. This allowed 25% brighter, sharper, and less distorted color pictures, earning Sony an Emmy Award in 1973—the first ever awarded to a Japanese corporation.
How did the Walkman revolutionize global consumer culture in 1979?
Released on July 1, 1979, the TPS-L2 Walkman was created at the request of co-founder Masaru Ibuka, who wanted to listen to opera cassette tapes during long international flights. By pairing a portable cassette player with lightweight headphones, Sony liberated music from living rooms and cars, inventing personal mobile audio and selling over 400 million Walkman devices across tape, CD, and digital formats.
How did Sony and Philips create the Compact Disc (CD)?
In 1979, Sony and Dutch electronics firm Philips agreed to co-develop a universal standard for optical digital audio. Launched commercially in October 1982 with the Sony CDP-101 player, the CD standard featured 16-bit digital audio and a 74-minute playing capacity, a duration specifically insisted upon by Sony executive Norio Ohga so that Ludwig van Beethoven's Ninth Symphony could be played without interruption.
How did Nintendo's betrayal lead to the creation of the PlayStation?
In 1988, Sony partnered with Nintendo to develop a CD-ROM drive add-on for the Super Famicom/SNES. At the Consumer Electronics Show (CES) in June 1991, Nintendo publicly betrayed Sony by announcing a rival partnership with Philips the day after Sony revealed the project. Enraged, Sony President Norio Ohga authorized engineer Ken Kutaragi to develop a standalone 3D gaming console, resulting in the December 1994 launch of the PlayStation, which went on to sell over 102 million units.
When did Sony expand from hardware manufacturing into entertainment content?
Under President Norio Ohga, Sony executed two massive acquisitions to marry hardware with entertainment content: purchasing CBS Records in January 1988 for $2.0 billion (renamed Sony Music Entertainment) and Hollywood movie studio Columbia Pictures Entertainment in November 1989 for $3.4 billion plus assumed debt (renamed Sony Pictures Entertainment).
What challenges did Sony face in the early 2000s "lost decade"?
In the early 2000s, Sony suffered from corporate divisional silos and conflicting digital rights management policies, allowing Apple's iPod and iTunes ecosystem to dismantle Sony's portable music dominance. Simultaneously, aggressive pricing and manufacturing agility from South Korean rivals Samsung and LG caused massive cumulative losses in Sony's cathode-ray and LCD television business.
How did Kazuo Hirai execute the historic "One Sony" corporate turnaround?
Appointed CEO in April 2012, Kazuo "Kaz" Hirai executed the "One Sony" restructuring strategy. He divested the unprofitable VAIO personal computer division, spun off the Bravia television business into an independent operating subsidiary, downsized Xperia smartphones, and concentrated capital into three core profit engines: PlayStation gaming, CMOS image sensors, and entertainment intellectual property, returning Sony to record profitability.
Why did Sony rename itself to "Sony Group Corporation" in April 2021?
On April 1, 2021, Sony Corporation changed its corporate name to Sony Group Corporation, marking its first company name change in over 60 years. The move symbolized its strategic evolution from an electronics hardware manufacturer into a diversified creative entertainment conglomerate with a solid foundation of cutting-edge technology.
