# Founding of Microsoft | Washington State History

## Definition

The founding of Microsoft was the 1975 start of the company by Bill Gates and Paul Allen. In Washington State History, it marks the beginning of the state’s rise as a major tech center.

## What It Is

The founding of Microsoft is the 1975 creation of the company by Bill Gates and Paul Allen, starting as a small software business that would later become one of Washington’s biggest economic engines. In Washington State History, it is not just a company origin story. It is a turning point in how the state developed a modern technology sector.

Microsoft began by building software for the Altair 8800, a microcomputer that helped open the personal computing market. Its first major product was a BASIC programming language version for that system. That detail matters because Microsoft was not originally a computer-maker. It was a software company, and that focus on software shaped both the business and the wider industry.

The company’s early growth connected Washington to a fast-changing national tech economy. When Microsoft released MS-DOS in 1981, it became tied to IBM PC systems and helped make the company a major force in personal computing. Later, Windows gave Microsoft a place in the graphical user interface era, when computers became easier for everyday users to operate.

For Washington, the larger story is that Microsoft helped shift the state’s image from one dominated by older industries into a center for high-tech jobs, investment, and corporate growth. The company’s success also encouraged a wider cluster of software talent, suppliers, and related businesses in the Seattle area and on the Eastside.

So when this term appears in a Washington history class, you should think about both the company and the place. The founding of Microsoft connects one startup to bigger themes like regional economic change, the rise of the software industry, and Washington’s long-term role in American technology.

## Why It Matters

The founding of Microsoft matters because it helps explain how Washington became one of the country’s best-known tech states. A single startup in 1975 turned into a company that changed software, jobs, tax revenue, and the state’s economic identity. That makes Microsoft a useful example of how one business can reshape a region over time.

It also gives you a concrete case for the shift from manufacturing and resource-based growth toward knowledge-based industries. In Washington State History, that shift shows up again and again in lessons about Seattle, the Eastside, and the growth of high-skill employment. Microsoft is one of the clearest examples because its products reached homes, schools, and offices across the world while its headquarters stayed in Washington.

This term also helps you connect local history to national technology trends. When a question asks why Washington became a tech hub, Microsoft is part of the answer alongside other firms, universities, and infrastructure. If you can explain Microsoft’s founding, you can explain more than a company timeline. You can explain a pattern of regional economic change.

## Connections

### [Microsoft](/hs-washington-state-history/key-terms/microsoft)

The founding of Microsoft is the start of the company itself, so this connection helps you separate the event from the larger business. When a question mentions Microsoft in Washington history, you may need to talk about the company’s creation, not just its later products. The founding is the starting point for its influence on the state’s tech economy.

### MS-DOS

MS-DOS shows what Microsoft did after it was founded. The company’s early success came from software, and MS-DOS became one of the products that made Microsoft a dominant force in personal computing. In a Washington history context, it shows how a local startup could grow into a national software powerhouse.

### Windows

Windows connects Microsoft’s founding to the era when computers became easier for ordinary users. It represents the next stage after Microsoft’s early software work, when the company expanded from basic programming tools into mass-market operating systems. In class, this often shows up as part of the story of Washington’s tech growth and global reach.

### [University of Washington](/hs-washington-state-history/key-terms/university-of-washington)

The University of Washington matters because Washington’s tech economy did not grow in isolation. Universities help produce skilled workers, research, and business networks that support companies like Microsoft. When you study the state’s tech sector, the university connection helps explain how talent and innovation stayed concentrated in the region.

## On the AP Exam

A timeline question may ask you to place Microsoft’s founding in 1975 and connect it to later changes in Washington’s economy. A short-answer or essay prompt might ask how one company helped turn the Seattle area into a technology hub. In that kind of response, name the founding, then explain the chain of effects: software sales, job growth, headquarters expansion, and the rise of a regional tech cluster.

If you get a document or chart about Washington industries, use Microsoft as evidence of the state’s move into high-tech business. If the question compares older industries with newer ones, Microsoft is a strong example of how software changed the economy without relying on factories or natural resources. The safest move is to link the founding date, the software focus, and the impact on Washington’s long-term growth.
