The Silicon Valley chipmaker whose co-founder Gordon Moore predicted that the number of transistors on a chip would double roughly every two years.
See it on the Innovation & Wealth map →What happened
In 1965 Fairchild's Gordon Moore predicted that the number of components on a chip would keep doubling, yearly at first, then (from 1975) every two years. In 1968 he and Robert Noyce left to found Intel, with $2.5 million raised by Arthur Rock; Andy Grove joined at the start. Intel made memory chips, then the first commercial microprocessor, the 4004 (1971). IBM's 1981 choice of its 8088 made Intel's x86 chips the PC standard and its profit engine.
Impact on society and the economy
Moore's law became the industry's roadmap: computing got exponentially cheaper for 50 years. Intel's dominance drew antitrust fines; it later lost its manufacturing lead to TSMC, and Washington took a roughly 10% stake in 2025.
How we know
Moore's 1965 Electronics article 'Cramming More Components onto Integrated Circuits,' Intel's filings, decades of chip-density data, and Michael Malone's history The Intel Trinity (2014).
Still debated
Whether Moore's law is ending is hotly debated: transistors still shrink, but the cost per transistor no longer falls as fast. Credit for the 4004 is shared among several engineers.
Connections (4)
▸Venture capital and Silicon Valley funded Intel and Moore's lawWell documented
The connection
When Noyce and Moore left Fairchild in 1968, Arthur Rock, who had arranged Fairchild's funding, raised $2.5 million for Intel within about two days, on the founders' reputations and a one-page business plan he typed himself. Rock became chairman. Intel's success showed investors how large a venture-backed start-up could grow.
When and how
Mountain View, California, July 1968; Rock, the founders and a small group of investors bought convertible debentures, a loan that can turn into stock.
How we know
Intel's founding records, Rock's own interviews, and filings at Intel's 1971 public offering document the funding.
Debates
There is little dispute over the funding; debate is over how much Intel's success came from venture money versus Fairchild-trained talent and military chip demand.
▸Intel and Moore's law partnered in the 'Wintel' era with Bill Gates and MicrosoftWell documented
The connection
IBM's 1981 PC paired Intel's 8088 chip with Microsoft's MS-DOS. As clone makers copied the PC, the Intel-chip and Microsoft-software pair became the standard, nicknamed 'Wintel' after Windows. Each new Windows version needed faster Intel chips, and each faster chip ran richer software, a cycle that made both firms dominant and very profitable through the 1990s.
When and how
IBM PC launched August 1981; Compaq's 1983 clone opened the market; 'Wintel' machines dominated PCs from about 1990 to 2010, around 90% of sales at the peak.
How we know
Market-share data, company filings, and the US v. Microsoft and FTC Intel case records document both firms' dominance and interdependence.
Debates
The partners were often rivals: Microsoft supported other chips and Intel pushed its own software. Regulators argued their dominance limited competition; how much consumers were harmed is disputed.
▸TSMC (Morris Chang) surpassed the chipmaking lead of Intel and Moore's lawWell documented
The connection
Intel long led the world in chip manufacturing, keeping pace with Moore's law in its own factories. In the 2010s its 10-nanometer process slipped years behind schedule, while TSMC, fed by huge orders from Apple and others, pulled ahead by about 2018. Apple dropped Intel chips for Macs from 2020, and Intel now outsources some chips to TSMC.
When and how
Santa Clara, California, and Hsinchu, Taiwan, about 2015–2020; Intel CEO Pat Gelsinger launched a comeback plan in 2021.
How we know
Product timelines, industry analyses and Intel's own public admissions of its 10nm and 7nm delays in 2018 and 2020.
Debates
Whether Intel's turnaround, backed by CHIPS Act funding and a US government stake taken in 2025, can restore its lead is uncertain.
▸Intel and Moore's law set the pace of Microchips and the personal computerWell documented
The connection
Intel's 4004 (1971) put a computer's processor on one chip, and later Intel chips like the 8080 and 8088 powered early PCs. Moore's law, co-founder Gordon Moore's forecast that chip density doubles about every two years, became the industry's planning target, so the whole sector raced to meet it, driving costs down year after year.
When and how
Mountain View and later Santa Clara, California; the 4004 was designed in 1969–71 for Japan's Busicom calculators by Federico Faggin, Ted Hoff, Stan Mazor and Busicom's Masatoshi Shima.
How we know
Chip-density data tracked Moore's forecast closely for decades, and the industry's shared roadmaps (1990s–2016) explicitly used it as a target.
Debates
Was Moore's law a natural trend or a self-fulfilling prophecy? Intel did not invent the integrated circuit itself; Texas Instruments and Fairchild did, in 1958–59.
