How Sony Built Its Entertainment Empire
Sony started making rice cookers and radio repair equipment in 1946. Today it owns PlayStation, Columbia Pictures, Sony Music, and the world's largest music publishing catalogue. Here is the full story.
In May 1946, Masaru Ibuka and Akio Morita founded Tokyo Tsushin Kogyo, the Tokyo Telecommunications Engineering Corporation, in a bombed-out department store in Tokyo with approximately 20 employees and initial capital of 190,000 yen. Their first commercially significant product was a rice cooker that did not work. Their second attempt at a consumer product was an audio tape recorder, built before magnetic tape was commercially available in Japan, using tape they made themselves by coating paper strips with magnetic powder mixed with lacquer.
That tape recorder found buyers at NHK, Japan's national broadcaster. It was the beginning.
Sony Group Corporation today is one of the most diversified entertainment and technology companies in the world. For fiscal year 2025 (ended March 31, 2025), the company reported approximately ¥13.0 trillion in revenue. It employs approximately 113,000 people. Its operations span consumer electronics and professional technology, music, film and television, gaming, semiconductors, and financial services. The PlayStation gaming division alone generates more than $25 billion in annual net sales.
This post traces the full arc: from the Tokyo electronics startup through the Walkman, the Columbia Pictures and CBS Records acquisitions, the PlayStation invention, and the entertainment empire that exists today.
The Founders and the Sony Name
Masaru Ibuka and Akio Morita were an unusual pairing. Ibuka was an engineer and inventor, fascinated by the challenge of creating consumer electronic devices. Morita was a businessman and communicator, focused on building brands and expanding markets. The combination proved exceptionally effective.
The company's name change from Tokyo Tsushin Kogyo to Sony in 1958 was strategic. Morita wanted a name that would be easy to pronounce and remember in Western markets. Sony combined "sonus," the Latin root for sound, with "sonny," an American slang term for a bright young person that was widely used in Japan at the time. The name was globally simple in a way that "Tokyo Telecommunications Engineering Corporation" was not.
The new name accompanied the company's listing on the Tokyo Stock Exchange in 1958 and its rapid international expansion.
The Transistor Radio and the Walkman: Defining Consumer Electronics
Sony's commercial breakout product was the TR-55, Japan's first commercially marketed transistor radio, introduced in 1955. Transistors had been invented at Bell Labs in the United States in 1947. Sony obtained a licence to the transistor patent for $25,000 and used it to develop radios small enough to carry in a shirt pocket. The pocket transistor radio made personal portable audio a mass consumer behaviour for the first time.
The product that most powerfully defined Sony's brand identity globally was the Walkman, introduced in July 1979. The Walkman, a portable cassette player with headphones, was the personal music player that created the concept of music-listening as a private, mobile activity. Over 400 million Walkman units across various formats were sold between 1979 and 2010.
The Walkman was followed by other format-defining products: the Betamax VCR (1975, which lost the format war to VHS but demonstrated Sony's capacity for product innovation), the CD player (co-developed with Philips and launched in 1982), and the first consumer camcorder (1983).
The Entertainment Acquisitions: CBS Records and Columbia Pictures
In the late 1980s, Sony made the strategic decision to expand from hardware into content. The logic was defensive as well as offensive: Sony's Betamax had lost to VHS partly because VHS had more pre-recorded movie titles available. A hardware company that also owned content would not face this problem.
CBS Records (1988): Sony acquired CBS Records, the largest music recording company in the world at the time, for approximately $2 billion. The acquisition, facilitated by Sony's Akio Morita and CBS Inc. chairman Laurence Tisch, created Sony Music Entertainment and gave Sony ownership of one of the deepest recorded music catalogues in existence, including artists from Miles Davis and Barbra Streisand to Michael Jackson and Bruce Springsteen.
Columbia Pictures (1989): Sony acquired Columbia Pictures Entertainment from Coca-Cola (which had owned it since 1982) for approximately $3.4 billion. Columbia's film library included Ghostbusters, Kramer vs. Kramer, and hundreds of other titles. Sony subsequently formed Sony Pictures Entertainment combining Columbia, TriStar Pictures, and related assets.
The entertainment acquisitions were controversial in the United States. Congressional hearings examined the cultural implications of Japanese ownership of major American entertainment assets. Books with titles like "The Coming War with Japan" reflected the anxieties of the era. Sony managed the controversy partly by maintaining American management at Sony Pictures.
The Columbia acquisition initially struggled commercially. Sony invested heavily in production slates under Jon Peters and Peter Guber that were largely unsuccessful, resulting in reported losses of approximately $3 billion in the early 1990s. The division stabilised under subsequent management and has since generated consistent returns through its Spider-Man franchise, James Bond (in partnership with MGM), and other properties.
PlayStation: The Gaming Division
PlayStation began as an internal Sony project in the late 1980s, initially conceived as a CD-ROM add-on for Nintendo's Super Nintendo console under a partnership agreement. That deal collapsed after Nintendo changed the terms unilaterally, leaving Sony's Ken Kutaragi with a partially developed CD-based game system and the determination to turn it into a standalone competitor.
PlayStation launched in Japan in December 1994 and in North America in September 1995. Its 32-bit processor and CD-based game library represented a significant leap over the 16-bit cartridge-based competitors (SNES, Sega Genesis). Sony's marketing positioned PlayStation for older teenagers and young adults rather than children, with launch titles including Ridge Racer and Tekken. By 1998, PlayStation had sold over 40 million units.
PlayStation 2, launched in 2000, became the best-selling gaming console in history with approximately 155 million units sold. PlayStation 3, 4, and 5 each became industry-leading platforms in their respective generations.
Sony Interactive Entertainment operates the PlayStation business as a division of Sony Group Corporation. As of early 2026, PlayStation 5 has sold approximately 74 million units since its November 2020 launch. PlayStation Network, the online gaming service, has approximately 116 million monthly active users. The PlayStation brand is Sony's largest single revenue contributor.
Bungie acquisition (2022): Sony acquired Bungie, the video game developer and creator of the Destiny franchise, for approximately $3.6 billion, adding a significant first-party game development studio.
Sony Music: The Music Empire
Sony Music Entertainment is one of the three major recorded music companies globally, alongside Universal Music Group and Warner Music Group. Following the merger with Bertelsmann Music Group (BMG) in 2004, which was later unwound, Sony Music has expanded through content acquisitions.
Sony Music Publishing: In 2021, Sony completed the acquisition of Michael Jackson's estate's 50% stake in the Sony/ATV Music Publishing joint venture for approximately $750 million, making Sony the sole owner of the world's largest music publishing catalogue. Sony Music Publishing controls the publishing rights to over 6 million songs, including the Beatles catalogue, Beyoncé, Queen, Bob Dylan, and Taylor Swift's pre-2019 catalogue.
Sony also acquired the music library of Bruce Springsteen for approximately $550 million in 2021 and has continued building its catalogue through strategic acquisitions.
Sony Pictures and the Spider-Man Deal
Sony Pictures Entertainment owns the film rights to Marvel's Spider-Man character, acquired through a licensing agreement with Marvel in 1999 before Marvel's own studio existed. When Marvel was acquired by Disney in 2009, Sony retained its Spider-Man film rights.
The Sony-Disney Spider-Man deal, announced in 2019, allows the character to appear in the Marvel Cinematic Universe while Sony retains the standalone rights. This arrangement has produced some of the highest-grossing films in Sony Pictures' history, including Spider-Man: No Way Home (2021), which grossed approximately $1.9 billion globally.
Sony Semiconductor: The Invisible Dominance
Sony is the world's dominant manufacturer of CMOS image sensors, the components that capture images in smartphones, digital cameras, security systems, and automobiles. Sony's semiconductor division holds an estimated 40-50% global market share in smartphone image sensors.
Sony's sensor technology underpins the cameras in Apple's iPhone, Samsung Galaxy, Google Pixel, and virtually every other major smartphone. The semiconductor business generates significant and growing revenue as camera technology in smartphones continues to advance.
