Probably they will start with the forerunners, with Llull and Babbage and Lovelace; and then turn to the true pioneers, to Turing and Church and Shannon and von Neumann; and then the masters of hardware, Noyce and Kilby, and of software too, Ritchie and Dijkstra; and eventually they will arrive at PageRank, recommendation systems, neural nets, the transformer architecture, and whichever system ended up bootstrapping itself into superintelligence and thus inaugurating an entirely new epoch of history. But somewhere in their chronicle of this grand arc, for at least a few pages, they will have to talk about the electronic spreadsheet.\nThe electronic spreadsheet. Is there any tool as ubiquitous and yet so unloved? It would not be an exaggeration to say that Microsoft Excel, the product that today defines the spreadsheet category, is the most successful piece of application software ever made, counting about a sixth of humanity among its users and deciding the terms on which trillions of dollars in capital are allocated. And yet you will struggle to find people who love the spreadsheet. You will find people who wax poetic about the beauty and elegance of certain pieces of software—about Linux, or Rust, or particularly fast Python package managers. But you will be hard-pressed to find a true admirer of Excel.\nAnd indeed that is a marker of a truly great tool. It is so ubiquitous that it has become, in a strange way, anonymous. But you cannot really understand the transformation of the American economy over the last few decades without understanding the spreadsheet.\nThis is a story about how a piece of software transformed the way that American businesses understood themselves, and how they were understood by others; how it enabled the rise of financial engineering and the entire apparatus of Wall Street dealmaking; how it helped reshape the American corporation from an organization that built things into an organization that optimized numbers; and how it offers us a lesson, and a warning, about how artificial intelligence will transform economic life.\nBut we should start with the world before Excel.\nThe world before the spreadsheet\nA company is a group of people who have agreed to coordinate their activities under a unified authority in order to produce something. In any company, there are people at the top, the managers. The managers exist, at the most basic level, as information processors: they process information, use that information to make decisions about the allocation of resources, and then issue orders to the people below them based on those decisions. They are “the brain of the firm.”\nAnd every company is bottlenecked by the processing power of its brain. The managers can only keep track of so many things at once; every new employee or project or division adds another node to the network of things that management has to keep track of, and the complexity of that network grows much faster than the number of nodes. So the capacity of its management to process information and coordinate action sets a natural limit on the size and complexity of any firm.\nThis is why, in the premodern world—when processing information and coordinating action were both extraordinarily expensive, because communication was slow and coordination outside of relatively small kinship groups was difficult—firms tended to be local concerns, centered either around families or similarly high-trust networks like monasteries. Almost every business in the world was a family business.\nThis changed with the rise of the steam engine. The mechanical power that the steam engine allowed people to harness brought a dramatic acceleration in the speed and volume and complexity of economic life: it greatly expanded opportunities for profit, but—because of its inherent danger and complexity—also demanded a great deal of control. You needed to be able to process all the complexity that the factory generated. And so, between the 1840s and 1920s, we see the emergence of technologies designed to communicate information and coordinate action at scale—the telegraph, the rotary power printer, the filing cabinet, the typewriter, the telephone, the punch-card processor, and the columnar pad.\nThis was the “control revolution.” With this new capacity for processing information and coordinating activity, we see the emergence of the modern corporation: much larger, more ambitious, and more centralized than any firm of the premodern period. It was a bureaucratic entity, operated by professional managers, designed to coordinate labor and capital at massive scale.\nThis was where the brain of the firm became a real thing. At a company like General Motors, hundreds of reports from the company’s operations would flood into headquarters every week; clerks would transcribe the figures from these reports onto columnar pads, long sheets of green-tinted paper ruled into columns and rows; and then they would feed the aggregated numbers to supervisors, who would summarize them further and pass them upward to managers, who would compare this month’s figures with last month’s figures, identify variance, propose explanations, compose typewritten memos about their findings, and eventually transmit decisions back down the hierarchy to be carried out. It was, for its time, a truly staggering apparatus.\nBut it was also a highly limited apparatus. The obvious flaw was that processing information was really labor-intensive: you needed armies of clerks merely to have the most cursory idea of what was going on inside your company. And this meant that more ambitious attempts at analysis weren’t feasible: there was a hard ceiling on the number and complexity of the questions that managers could ask about their companies. Looking at how companies operated in 1920 or 1950, you would be struck by how much guesswork was involved in their attempts to understand why one thing was happening and another was not. They were flying blind.\nThe birth of the spreadsheet\nAnd as with so many other things, this equilibrium was upset by Moore’s Law. It was inevitable, as microprocessors got cheaper and more powerful over the course of the 1960s and ‘70s, that someone would figure out how to represent the accounting functions of the corporate world on a computer. And that someone, as it turned out, was a 27-year-old engineer named Dan Bricklin.\nBricklin had studied computer science at MIT, and then spent a few years building word-processing software for Digital Equipment Corporation, the company that pioneered the minicomputer; but he felt drawn to the business side of things, and in the late 1970s decided to leave DEC to study at Harvard Business School. And sitting in a Harvard classroom in 1978, watching as a professor used a blackboard to work through the complex and interlocking calculations involved in determining the valuation of a company, Bricklin realized that you could just do all of this on a computer. You could simply make, he said, “a word processor that would work with numbers.” And thus was born the idea of the electronic spreadsheet.\nBricklin decided that this idea was gold and would represent his foray into entrepreneurship. So he teamed up with a friend of his from MIT named Bob Frankston, founded a company they called Software Arts, and spent most of 1978 and 1979 bringing the vision of the electronic spreadsheet to life.\nIt was, as it turned out, an intensely difficult problem. Bricklin and Frankston were designing their package for the Apple II, which had hundreds of thousands of times less memory than a modern laptop. The resource demands for word processing had been manageable, since a document is ultimately a stream of characters stored sequentially in memory; but spreadsheets were an entirely different game. Each cell carried a value, a formula, formatting, and dependency information, and the memory required to store all of this added up fast; a grid of any useful size threatened to exhaust the machine’s capacity entirely.\nAnd so Bricklin and Frankston had to be extraordinarily precise in how they used every byte. They wrote the entire package in assembly code for the Apple II’s 6502 microprocessor, stored cells in fixed 32-byte chunks in order to minimize overhead, and represented values in variable-length formats with type indicators such that small values would consume only a few bytes. And even after all this ingenuity, the resulting spreadsheets were small by modern standards: VisiCalc’s grid extended to just 63 columns and 254 rows, a tiny canvas compared with what a spreadsheet user today takes for granted, but enough to transform the work of anyone who sat down at it. Every design decision was, at bottom, a decision about how to save on memory.\nAnd their attention to detail paid off. They called the software package they produced “VisiCalc”—the visible calculator—and released it for the Apple II at the end of 1979. And it really was a marvel of software engineering. It was a brilliant fusion of the organizational metaphor of the columnar pad with the interactivity of word processing and the speed of the microprocessor. You could now calculate and recalculate things instantly; you could execute complex formulas programmatically instead of by hand; and things that would have once taken you hours now took you a few minutes. VisiCalc was an extraordinarily powerful tool. And it made the Apple II, which had been a hobbyist device, a useful business machine. Indeed so potent was VisiCalc that the Apple II was sold, as the journalist John Markoff wrote, mainly as a “VisiCalc accessory.” It was the first piece of software so compelling that people bought hardware specifically to run it: the first of the “killer apps.”\nBut Software Arts, having brought the electronic spreadsheet to life, did not define the category for long. Bricklin and Frankston were computer scientists at heart, and in the years after VisiCalc’s release they poured resources into TK!Solver, a niche program targeted at engineers and scientists; and so they were slow to port VisiCalc to the personal computer that IBM released in 1981, which quickly came to dominate the business market.\nThat opportunity was seized instead by a man named Mitch Kapor. Kapor had once been a full-time teacher of transcendental meditation, before working as head of development at VisiCorp, the company that marketed and distributed VisiCalc; and, seeing the opportunity in the electronic spreadsheet market, he decided to start a competitor. At the start of 1983, his company, Lotus, released the Lotus 1-2-3 electronic spreadsheet, purpose-built for the IBM machine. Lotus 1-2-3 was a significant improvement over VisiCalc—it offered charts and rudimentary database functionality along with the basic spreadsheet, and it could handle vastly larger grids, offering 256 columns and over eight thousand rows—and so Kapor quickly outcompeted Bricklin and Frankston. Software Arts floundered, and was sold to Lotus in 1985; and Lotus spent the next few years as the unchallenged market leader in spreadsheets. It even had, at the peak of its powers, its own magazine.\nBut the era of Lotus dominance did not last long either. VisiCalc and Lotus 1-2-3 were both keyboard-driven, text-based programs, navigated with arrow keys; but the future, as recognized by an ambitious Seattle-based software firm called Microsoft, was in the graphical user interface, the GUI. With the GUI you could replace typed commands and keystrokes with direct visual manipulation, such that", "url": "https://wpnews.pro/news/seeing-like-a-spreadsheet", "canonical_source": "https://davidoks.blog/p/how-the-spreadsheet-reshaped-america", "published_at": "2026-03-25 21:08:58+00:00", "updated_at": "2026-05-22 09:06:02.441546+00:00", "lang": "en", "topics": ["products", "enterprise-software", "data", "research"], "entities": ["Microsoft Excel", "Llull", "Babbage", "Lovelace", "Turing", "Church", "Shannon", "von Neumann"], "alternates": {"html": "https://wpnews.pro/news/seeing-like-a-spreadsheet", "markdown": "https://wpnews.pro/news/seeing-like-a-spreadsheet.md", "text": "https://wpnews.pro/news/seeing-like-a-spreadsheet.txt", "jsonld": "https://wpnews.pro/news/seeing-like-a-spreadsheet.jsonld"}}
