The First Computers Were Military and Corporate Machines

The earliest computers—ENIAC, built in 1946, and UNIVAC, completed in 1951—were enormous machines that filled entire rooms and cost hundreds of thousands of dollars. Only governments, large corporations, and universities could afford them. These machines were used for military calculations, census work, and business accounting. The general public had no way to buy or use them.

Throughout the 1950s and 1960s, computers remained locked behind institutional walls. A person could see a computer only if they worked for a defense contractor, a bank, or a research lab. Most Americans knew computers existed but had never touched one and had no reason to think they ever would.

Key Takeaways

  • The Apple II, released in 1977, was the first computer designed and priced for individual home use, starting at $1,298.
  • The IBM Personal Computer arrived in 1981 and became the standard that most home and office computers followed for decades.
  • Personal computers remained expensive and required technical knowledge until the mid-1980s, when prices dropped and software became easier to use.
  • The graphical user interface, introduced by Apple's Macintosh in 1984, made computers accessible to people who had never programmed or used a command line.

Apple II Made Home Computing Possible in 1977

The Apple II, introduced by Steve Jobs and Steve Wozniak on April 16, 1977, was the first computer sold as a finished product ready to plug in and use. It cost $1,298—roughly $6,500 in today's money—which was expensive but within reach for some families and small businesses. It came with a keyboard, a power supply, and a case. You did not have to assemble it yourself or understand electronics to turn it on.

The Apple II had a color screen, a built-in speaker, and slots where you could add memory or other components. It ran programs written in BASIC, a programming language designed to be readable. Hobbyists and small business owners began buying them. The computer was still a specialized tool—you needed to know how to type commands—but it was no longer a secret government weapon.

IBM Personal Computer Set the Standard in 1981

The IBM Personal Computer, released on August 12, 1981, changed which computers people actually bought. IBM was a trusted name in business machines, and when the company entered the personal computer market, it gave the product when ready credibility. The IBM PC cost between $1,565 and $4,290 depending on memory and storage, and it ran an operating system called MS-DOS.

IBM's decision to let other companies build compatible machines meant that dozens of manufacturers could make IBM-compatible computers. This competition drove prices down and created a standard that the industry followed for decades. By the mid-1980s, IBM-compatible computers outsold Apple machines in offices and homes.

Graphical Interfaces Made Computers Usable Without Programming

Early personal computers required you to type commands into a black screen. You had to remember what to type and spell it correctly, or the machine would not understand you. This kept computers out of reach for most people, even after they became affordable.

The Apple Macintosh, released on January 24, 1984, introduced a graphical user interface to a mass-market computer. Instead of typing commands, you moved a mouse to click on pictures called icons. Windows showed you what was inside folders. This way of working was so intuitive that people with no technical training could learn it in minutes. The Macintosh cost $2,495, which was expensive, but the interface made it worth the price to many people who had been intimidated by earlier computers.

Prices Dropped and Software Became Practical in the Mid-1980s

Between 1984 and 1990, the price of a capable personal computer fell from around $2,500 to under $1,000. Memory became cheaper. Hard drives became standard. Printers that worked with home computers became affordable. Software companies began writing programs for ordinary tasks—word processing, spreadsheets, databases—instead of only for programmers and engineers.

By 1990, owning a computer was no longer a luxury or a hobby. It was becoming a practical tool for writing, managing money, and running a small business. Schools began teaching computer skills. Libraries started offering public access to computers. The shift from "computers are for experts" to "computers are for everyone" happened in roughly a decade.

The Internet Made Computers Essential After 1995

Personal computers existed and were becoming common, but most people still did not own one in 1990. The turning point came when the World Wide Web became public and internet service became available to homes. Suddenly, a computer was not just a tool for work—it was a way to find information, communicate, and shop.

Between 1995 and 2000, computer ownership in American homes jumped from about 25 percent to over 50 percent. The internet made computers essential rather than optional. People who had never considered buying one realized they needed one to stay connected.

Frequently Asked Questions

Did anyone actually buy computers in the 1970s?

Yes, but in small numbers. The Apple II sold about 2.7 million units between 1977 and 1985, mostly to hobbyists, small business owners, and schools. Commodore and Radio Shack also sold computers to home users. These were niche products, not mainstream, but they proved there was a market for personal computers.

Why did IBM's computer become the standard instead of Apple?

IBM allowed other companies to make compatible machines, which created competition and drove prices down. Apple kept tight control over its design and manufacturing, which kept prices higher. By the late 1980s, IBM-compatible computers dominated offices and homes because they were cheaper and more widely available.

Could you use a 1980s personal computer for the same things we use computers for today?

No. Early personal computers had tiny amounts of memory and storage by today's standards. They could run word processors, spreadsheets, and straightforward databases, but not video, music, or graphics-heavy programs. The internet did not exist on them. They were tools for specific tasks, not general-purpose machines like modern computers.

When did computers become cheaper than a car?

By the early 1990s, a capable personal computer cost $500 to $1,500, which was less than a used car but still a significant purchase for most families. By 2000, budget computers cost $300 to $500, making them cheaper than most used vehicles. This price point made computer ownership truly mainstream.
