When computers were first created, they were enormous. They would often take up the better part of a building, and they consumed an incredible amount of power. Despite the size of these early computers, some people saw a future where computers would shrink down small enough that they could fit inside a person's home. Though some thought that the idea was ridiculous, not only was that prediction true, but it has changed everything. Learn more about the history of personal computing and how it developed on this episode of Everything Everywhere Daily. Did you ever hear about the selfie that solved a murder or the jury that used a Ouija board to speak to a victim? If that made you pause, you need to listen to Morning Cup of Murder.

I'm Karina Bimus Durfer, and every single day on Morning Cup of Murder, I tell one chilling true crime story tied to that exact day in history. With over 2,500 episodes to binge, you'll never run out of dark stories to start your morning with. Go listen to Morning Cup of Murder wherever you get your podcasts. And remember, stay safe. In hindsight, given the world that we live in today, it's hard to believe that there was a time

when the idea of a personal computer was considered ludicrous. Before the advent of personal computers, computing was the exclusive domain of governments, universities, and large corporations. The earliest electronic computers, such as ENAC in 1945 and UNIVAC in 1951, were massive machines that filled entire rooms, required teams of specialists to operate,

and cost millions of dollars. These mainframe computers were primarily used for complex scientific calculations, processing census data, and military applications. The concept of an individual owning a computer was absurd during this era. Yet, even at this early stage, some people with foresight saw a future where computing devices would be personal. One such person was Vannevar Bush. Bush was an American engineer, inventor, and science administrator, who was the head of the

U.S. Office of Scientific Research and Development during World War II. He laid out a vision of a personal knowledge machine in 1945 with a device he called Memex, a desk-sized device for filing, linking, and retrieving one's own documents using associative trails. He didn't describe a microprocessor or a graphical user interface, but he nailed the idea of a privately owned interactive information appliance that augments an individual's memory and creativity. The real transition to towards smaller, more accessible computers began in the 1960s with the development of mini-computers. Companies like Digital Equipment Corporation pioneered this movement with machines like the PDP8, which was roughly the size of a refrigerator rather than a room.

While still expensive and requiring technical expertise, mini-computers represented a significant step towards democratizing computing power. During this time, Joseph Carl Robnett Licklider shifted from the notion of information storage to active human partnership. In his groundbreaking 1960 paper Man Computer Symbiosis, and later with his work at DARPA, he argued that interactive computing would be personal, conversational, and networked. His vision of an intergalactic network implied many people at many small consoles, not a few mainframes serving batch jobs. Douglas Engelbart turned this into a working preview.

His 1962 program to augment human intellect and the 1968 mother-of-all-demo, which you may recall from a previous episode, showcased a single user interacting with a high-resolution display featuring a mouse, windows, real-time editing, hyperlinks, and video collaboration. He demonstrated a personal workstation decades before the concept was adopted by the market at scale. The true foundation of personal computing emerged in 1971 when Intel developed the Intel 4004, the first commercially available microprocessor. This single chip contained the processing power that previously required entire circuit boards.

The 4004 was followed by more powerful processors, including the Intel 800, and then crucially the Intel 8080 in 1974, which became the heart of many early personal computers. The microprocessor represented a paradigm shift because it made computing power both affordable and compact enough to be accessible to individuals and small organizations. This technological breakthrough set the stage for the personal computer revolution that would follow. The first true personal computer is often considered to be the Altair 8800, introduced by micro-instrumentation and telemetry systems, or Mitz, in January of 1975. Featured on the cover of Popular Electronics magazine, the Altair captured the imagination of electronics hobbyists despite its limitations. The Altair 8800 used an Intel 8080-CPE,

running at about 2 megahertz with a base memory of 256 bytes, expandable up to 64 kilobytes. It had no keyboard, no screen, and it came as a kit requiring assembly. Users programmed it by flipping switches in the front panel and received output through blinking lights. Despite these constraints, the Altar 8800 sold thousands of units and demonstrated that there was genuine demand for personal computers. The Altair's success attracted the attention of two young programmers, Bill Gates and Paul Allen, who developed a version of the Basic programming language for the machine. This marked the beginning of their company, which they named after the Micro Computer Software, Micro Soft. Their work on the Altair Basic demonstrated the critical importance of software,

not just hardware, in making personal computers practical and accessible to non-technical users. Around the same time, the Homebrew Computer Club, formed in Silicon Valley, bringing together enthusiasts, engineers, and entrepreneurs who shared ideas and innovations. This informal gathering became a breeding ground for innovation and personal computing, and among its members were Steve Wozniak and Steve Jobs. Wosniak, while still working at Hewlett-Packard, designed the Apple One computer in 1976 primarily for his own use and to impress fellow members of the Homebrew Computer Club. His friend Steve Jobs recognized the commercial potential and convinced Wozniak to start a company with him.

The Apple One was sold as a fully assembled circuit board, and users still needed to provide their own case, power supply, keyboard, and display. The two sold about 200 units from Jobs' parents' garage, establishing the Apple Computer Company. The real breakthrough came with the Apple II. Introduced in 1977, the Apple II was revolutionary because it was a complete ready-to-use system with a plastic case, integrated keyboard, color graphics capacity, and expansion slots for additional functionality. Wozniak's engineering created a machine that was both powerful and user-friendly. The addition of VisiCalc, the first spreadsheet program in 1979, transformed the Apple II from a hobbyist toy into a serious business tool. The Apple II became an enormous success, selling millions of units

and establishing Apple as a major player in the industry. The year, 1970s, also saw the introduction of two other significant personal computers that would define the first generation of mainstream machines. Besides the Apple 2, the Commodore Pet, or Personal Electronic Transactor, and the Tandy Radio Shack TRS-80 both debuted. The Commodore Pet was equipped with an integrated monitor, keyboard, and cassette tape drive in a distinctive all-in-one design. The TRS80, sold through Radio Shack's extensive retail network,

became popular due to its relatively low price and widespread availability. These three machines, often referred to as the 1977 Trinity, brought personal computing to a broader audience and established the market's viability. It was Commodore who made the first personal computer that I ever remember seeing, the VIC-20 in 1981. The VIC-20 sold for about $300, and my friend Tim had one in grade school. The computer was inside the keyboard and you just had to hook it up to a television. We would purchase computer magazines that had codes for games like Load Runner, inside. To play the game, we had to copy the code from the magazine without making a single error. We could then save it onto a cassette tape. The landscape of personal computing transformed

dramatically when IBM entered the market in August of 1981 with the IBM Personal Computer, commonly known as the IBM PC. IBM, who was the dominant force in mainframe computing at the time, had initially dismissed personal computers as insignificant. However, recognized the growing market, IBM assembled a team to quickly develop a personal computer. In an unprecedented move for IBM, the team decided to use off-the-shelf components and an open architecture, making design specifications publicly available. IBM chose Intel's 8088 processor for the CPU, and crucially, licensed an operating system from the small previously mentioned company, Microsoft. Bill Gates and Microsoft purchased an existing operating system called QDOS,

which stood for Quick and Dirty Operating System. They then modified it and turned around and licensed it to IBM as PC DOS, while retaining the rights to sell their own version MS DOS to other manufacturers. This decision would prove to be one of the most consequential business decisions in the history of computing. The IBM PC's open architecture meant that, other manufacturers could legally create compatible machines, leading to the proliferation of IBM PC clones or IBM compatibles. Companies like Compact, which reverse-engineered IBM's BIOS to create

fully compatible machines, led this charge. The standardization around IBM PC architecture and MS-DOS created a massive software ecosystem, as developers could write programs that would run on any compatible machine. This network effect made the IFCs. IBM PC platform increasingly dominant. Commodore also introduced the Commodore 64 in 1982, which became the best-selling single-computer model of all time, with estimates of 12 to 17 million units sold. The Commodore 64 was powerful, relatively inexpensive,

and became especially popular for gaming and home use. As IBM-compatible PCs proliferated, Microsoft's MS-DOS became the standard operating system for personal computers. Microsoft maintained control over the operating system while hardware manufacturers competed on price and features, creating a highly profitable situation for the software company. Bill Gates's vision of a computer on every desk and in every home running Microsoft software was close to becoming a reality. While the IBM PC was achieving market dominance through standardization, Apple was pursuing innovation in user interface design.

In 1983, Apple introduced the Lisa, the first commercial personal computer with a graphical user interface featuring windows, icons, menus, and a mouse. It was the closest implementation to date of Douglas Engelbart's vision in the mother of all demos. The Lisa was revolutionary, but failed commercially due to its high price of nearly $10,000 and slow performance. However, Steve Jobs was simultaneously overseeing another project that would succeed where the Lisa failed. The Macintosh,

introduced in January of 1984 with a famous Super Bowl commercial directed by Ridley Scott, brought the graphical user interface to a broader market at a more affordable price. The Macintosh featured a mouse, a bitmap display, and an intuitive interface that made it far easier to use than DOS-based PCs. The Mac popularized concepts like drag and drop, point-and-click, and visual metaphors like the desktop and a trash can. In 1985, Microsoft introduced Windows 1.1.2. a graphical user interface that ran on top of MS DOS.

While initially crude and not particularly successful, Windows represented Microsoft's answer to the graphical interfaces being pioneered by Apple. Subsequent versions, particularly Windows 3.0 in 1990 and Windows 3.1 in 1992, gained significant market adoption. However, it was Windows 95, released in August of 1995, that truly revolutionized personal computing with its user-friendly interface, plug-and-play hardware support, and integration of DOS and Windows

into a single product. Windows 95 launch was a cultural phenomenon with extensive marketing and millions of copies sold. The launch of Windows 95, which I remember vividly having been invited by Microsoft to one of their launch events, marked a transition in personal computing. With it, graphical user interfaces became the norm,

and personal computers became even more mainstream, especially with the rising popularity of the internet. 1995 was obviously not the end of personal computing, but I'm going to save the rest of that for a future potential episode. That being said, it should be noted that two of the very earliest personal computer companies, both founded by pioneering enthusiasts, remain operational today, and are among the largest companies on Earth. The combined market capitalization of both Apple and Microsoft,

is, as of the time I am recording this, $7.73 trillion, which is not bad for a couple of companies that were started in a garage. The original personal computers from the 1970s and early 80s are now collector's items. An original Altair 8800 now sells for thousands of dollars and an original Apple One just sold for $475,000 at auction.

While computers did a great, great deal of important work in the 1950s, 60s, and 70s, it really wasn't until computers became personal that they truly revolutionized society.
