Sony: The Empire That Lost to Itself

In the bombed-out ruins of Tokyo in 1946, a defense engineer named Masaru Ibuka and a younger physicist named Akio Morita founded a company with about five hundred dollars of borrowed capital and no clear idea of what to make.

Their first product, a rice cooker, failed. But the two men formed one of the most productive partnerships in business history, Ibuka the engineering genius obsessed with building things no one else could, Morita the marketer and leader with an uncanny feel for what consumers would want before they knew it themselves. They named their company Tokyo Tsushin Kogyo, then, in 1958, chose a short, punchy name that would work in any language: Sony. And they set out, from a defeated and impoverished nation, to make the words “Made in Japan,” then a synonym for cheap junk, into a mark of the finest quality in the world.

They succeeded beyond any reasonable hope. Sony sold one of the first transistor radios in the 1950s, shrinking music down to something a person could carry. It built the Trinitron, the color television whose picture was so superior it dominated living rooms for a generation. And in 1979 it produced the device that defined it forever: the Walkman, the small cassette player that, for the first time in history, let a person carry a personal soundtrack everywhere, in private, through headphones. It was a cultural revolution disguised as a gadget, and it made Sony the coolest, most innovative, most desirable technology brand on the planet. Sony was, in every meaningful sense, the Apple before Apple.

It is worth dwelling on the philosophy that drove all this, because it explains both the triumph and the tragedy. Morita’s founding creed was that Sony should never follow the market but lead it; rather than ask consumers what they wanted, it would build things they did not yet know they needed and create the demand. This produced the Walkman, which focus groups would never have asked for. But that same pride had an early warning sign. In the videocassette wars of the 1970s and 1980s, Sony’s Betamax format was widely considered technically superior to the rival VHS standard, yet Sony lost the market decisively, because it kept the format closed and proprietary while the VHS camp licensed theirs openly to anyone, winning on ubiquity rather than quality. It was the first clear sign of a fatal pattern: Sony’s conviction that the best, most tightly controlled technology would always win, in an industry that increasingly rewarded open standards instead.

The Empire, and the Seeds of the Fall

At its height, Sony made two decisions that would define both its glory and its coming crisis. The first was to expand from making hardware into owning content. Reasoning that its devices needed something to play, Sony bought CBS Records in 1988 and Columbia Pictures in 1989, becoming not just an electronics company but one of the world’s great music labels and film studios. The second, launched in 1994, was the PlayStation, a video-game console that would grow into one of the most successful entertainment platforms ever created and, eventually, the most reliable profit engine the company had.

On paper, this was an extraordinary collection of assets: the world’s best hardware, a major music catalog, a Hollywood studio, and a dominant gaming platform, all under one roof. Sony seemed positioned to own the digital future completely. And then it proceeded to lose that future, in the most instructive way imaginable.

The trouble was that Sony’s greatest strength, its mastery of self-contained, beautifully engineered hardware, curdled into its greatest weakness in an age of open standards and software. The company became infamous for a parade of proprietary formats, its own memory cards, its own disc standards, its own everything, designed to lock customers into the Sony world and to protect, above all, its content business from piracy. Its divisions, once a source of strength, hardened into warring fiefdoms that would not cooperate. And the whole culture suffered from a deep case of “not invented here,” an inability to embrace ideas and standards that originated outside its own walls.

The iPod Sony Should Have Built

Nowhere did this prove more catastrophic than in music, and the episode is one of the most important in all of business, because Sony, of all companies, should have built the iPod.

Consider its position at the dawn of the digital-music era around the year 2000. Sony had invented portable personal music with the Walkman and owned the brand that defined it. It made superb hardware. And, uniquely, it owned one of the world’s largest music catalogs through Sony Music. No company on Earth was better placed to create the device and service that would let people carry their entire music collection in their pocket. The combination of hardware mastery and music ownership was precisely what the moment demanded.

The same disease spread through the empire. In televisions, Sony clung to its expensive Trinitron tradition while Samsung and LG moved faster and cheaper into flat panels, and Sony’s TV business bled money for years. Its mobile phones never found their footing. By the late 2000s the company that had once defined consumer electronics was posting losses, shedding its reputation, and watching nimbler rivals take market after market. Around 2012, after years of red ink, Sony’s credit rating was cut to the edge of junk. The proudest name in technology had become a case study in how a great company declines: not through a single catastrophe, but through pride, internal division, and an attachment to the very things that had made it great.

The Reversal: The Humility to Stop Fighting the Wrong Wars

Sony’s recovery, beginning in earnest when Kazuo Hirai became chief executive in 2012 and accelerating under Kenichiro Yoshida from 2018, is a masterclass in the hardest discipline in business: the willingness to abandon glory.

Hirai and Yoshida grasped a painful truth: Sony could not win the commodity-hardware wars, and it should stop trying. So they did the unsentimental work of retreat. They sold off the VAIO personal-computer business entirely. They spun the struggling television operation into a separate unit and stopped chasing market share at a loss. They pulled the money-losing smartphone business back from its destructive fight for volume. They stopped, in short, trying to be the Sony of old, the company that had to win in every consumer-electronics category through sheer hardware excellence.

And then they did the constructive half: they poured resources into the businesses where Sony could actually build a durable, defensible advantage. They invested heavily in the PlayStation, turning gaming, with its recurring software and network revenue, into the company’s profit engine. A game console is sold at thin margins, sometimes at a loss, but every console plants a customer in an ecosystem that pays for years: full-priced games, a cut of every third-party title, online-network subscriptions, downloadable content. It is a razor-and-blades model with a network effect on top, and the switching cost of a library of purchased games and online friends locks players in, exactly the kind of recurring, defensible revenue the old hardware Sony, selling a television once and never hearing from the buyer again, had never possessed. They expanded the music business, which, after the catalog they had once tried so hard to protect, became a gusher of cash as streaming revived the entire recorded-music industry and Sony collected royalties on one of the largest catalogs in the world. And, most cannily of all, they doubled down on a quiet, almost invisible business: image sensors, the tiny chips that capture light inside digital cameras. Sony had become the world’s dominant maker of these sensors, supplying them to nearly every major smartphone manufacturer on Earth, including its old nemesis Apple, whose iPhones see the world through Sony’s eyes. It was a near-monopoly in an essential component, exactly the kind of unglamorous, high-margin, defensible business the old Sony had been too proud to prize.

The transformation worked. The company that had been left for dead returned to sustained profitability, its earnings reaching record highs, its mix shifted decisively from low-margin commodity gadgets toward high-margin platforms, components, and content. Sony had reinvented itself, not by becoming cool again, but by becoming disciplined.

What Everyone Got Wrong

The world misjudged Sony, in both directions, for years.

Mistake #1: “Sony will produce the next world-conquering gadget.” Reality: Its future was never another Walkman; it lay in unglamorous components, platforms, and content.

Mistake #2: “Owning the music and the hardware is an unbeatable edge.” Reality: That very combination caused the internal civil war that let Apple take digital music.

Mistake #3: “A declining legacy giant can’t truly come back.” Reality: Sony returned to record profits, not by reclaiming glory but by ruthless refocusing.

Mistake #4: “The boring businesses don’t matter; the famous products do.” Reality: The invisible image sensor and the gaming platform, not the iconic gadget, saved the company.

The Honest Present

The framework demands honesty about the present, and the present is a company transformed but facing the ordinary challenges of a mature conglomerate. Sony in 2026 is a diversified entertainment-and-technology group worth well over a hundred billion dollars, anchored by a dominant gaming platform, a quiet near-monopoly in image sensors now deepening through a new manufacturing partnership, one of the world’s great music catalogs riding the streaming boom, and a Hollywood studio. It is profitable, durable, and far healthier than the company that nearly collapsed.

But it is also a sprawling conglomerate whose very diversification invites the perennial question of whether its parts are worth more separated than combined, its growth is steadier than spectacular, and it competes in every one of its markets, in gaming, in sensors, in content, against formidable and well-funded rivals. The stock has been a laggard at times, reflecting the market’s uncertainty about how to value so many different businesses under one roof. The empire that lost to itself has been rebuilt on firmer ground, but it is the solid, diversified strength of a survivor, not the world-conquering dominance of its youth.

Why This Matters to Investors

Sony is the rare company in this collection that lived the full arc twice, soaring, collapsing, and rebuilding, and its lessons are unusually practical. The first is that the best businesses are often the unglamorous, defensible ones: an investor who recognized that the new Sony of image sensors and gaming was a stronger enterprise than the famous old Sony of gadgets saw value the nostalgic crowd missed. The second is the supreme importance of capital allocation that exits losing businesses, the hardest and most value-creating discipline a management can show. And the third is a warning: that the deadliest threats to a company are often internal, that divisions at war and pride in a legacy can destroy a firm more surely than any competitor. Studying Sony trains an investor to look past a famous brand to the actual economics beneath it, and to prize management willing to abandon glory for returns. None of this is investment advice.

Lessons in Order of Depth

On the surface: the Method

There is profound and underrated value in unglamorous, defensible businesses. Sony’s salvation came not from a glamorous new gadget but from image sensors, the invisible components inside other companies’ products, and from the recurring revenue of a gaming platform and a music catalog. Prize the boring, high-margin, hard-to-replicate business over the exciting, famous, but commoditized one; the picks-and-shovels supplier and the toll-collecting platform often make far better long-term businesses than the maker of the glamorous end product everyone actually recognizes.

Below the surface: the Money

Sony’s turnaround is a case study in the hardest form of capital allocation: exiting losing businesses. Hirai and Yoshida created enormous value not by what they built but by what they were willing to abandon, the PCs, the share of TVs, the fight for phone volume, redirecting that capital toward gaming and sensors where the returns were real. The discipline to kill or sell a beloved, legacy, but losing business is one of the rarest and most valuable traits in management, pride in a famous product is the enemy of good capital allocation, and a company willing to shrink the wrong parts of itself to grow the right ones deserves close attention.

Below that: the Mind

Sony’s fall is one of the great psychological lessons in business about how internal division and attachment to control destroy a company from within. Sony lost the future not to a superior competitor but to itself: its divisions, each protecting their own interests, made it structurally incapable of building the very product, the iPod, that its unique combination of assets made it best positioned to create. The deadliest threats to an organization are usually internal, a culture of fiefdoms and “not invented here” can paralyze even the most talented company, and an obsession with controlling and protecting what you have can blind you to the necessity of cannibalizing it before someone else does.

At the deepest level: the question it leaves us

Sony forces us to think about identity, and about the painful truth that survival sometimes requires letting go of who you were. For decades Sony’s identity was bound up in being the maker of the world’s most desirable consumer electronics, and that very identity became the prison that nearly destroyed it, because it could not stop fighting to be that company even as the ground shifted beneath it. Its recovery required a kind of grief: accepting that the glorious Sony of the Walkman was gone and would not return, and building something quieter in its place. The deepest question Sony leaves us is whether we, as individuals and institutions, can summon the same hard wisdom, to recognize when the identity that brought us our greatest success has become the obstacle to our continued life, and to find the humility to release it; because the alternative, clinging to a glorious past until it drags us under, is the more common and comfortable path, and it is the one that turns great companies, and great people, into monuments to what they used to be.

Frequently Asked Questions

Who founded Sony, and when?

Sony was founded in May 1946 in the ruins of postwar Tokyo by Masaru Ibuka, an engineer, and Akio Morita, a physicist and marketer, originally as Tokyo Tsushin Kogyo (Tokyo Telecommunications Engineering Corporation). It renamed itself Sony in 1958. Ibuka’s engineering genius and Morita’s marketing mastery formed one of the most productive partnerships in business history.

What made Sony so dominant in its golden age?

A run of category-defining products built on superb engineering: one of the first transistor radios (1955), the Trinitron color television (1968), and above all the Walkman (1979), which invented portable personal music. These made Sony the most admired and desirable consumer-electronics brand in the world, much as Apple would later become.

Why did Sony lose digital music to Apple?

Through internal civil war. Sony had every advantage, it invented the Walkman and owned a major music label, but its hardware and music divisions clashed: the music side, fearing piracy, insisted on crippling, proprietary formats that made Sony’s players hostile to use. Apple, owning no label, built the seamless iPod and iTunes and took the entire category Sony had created.

How did Sony turn itself around?

Under CEOs Kazuo Hirai (from 2012) and Kenichiro Yoshida (from 2018), Sony stopped fighting losing battles. It sold its VAIO PC business, restructured TVs, and pulled back its money-losing phone unit, then reinvested in defensible businesses: the PlayStation gaming platform, its music catalog, film and television, and above all image sensors, where it became the world’s dominant supplier, including to Apple.

What is Sony’s business in 2026?

A diversified entertainment-and-technology group worth roughly $125-138 billion, spanning gaming (PlayStation), image sensors (a near-monopoly in smartphones, now deepening via a partnership with TSMC), music, film and television, and financial services. It is profitable and durable, though as a sprawling conglomerate it faces questions about whether its parts are worth more apart, and its growth is steady rather than spectacular. None of this is investment advice.
