The twelve milestones below show how: some were components or research programs, while others were prototypes or products people could buy. They are a curated selection, not a definitive ranking—and the date attached to each marks a particular milestone, not always the moment an idea was first conceived or became widely available.
Computing moved toward the individual
Small computing components and early personal machines helped shift computing away from centralized systems and toward devices intended for individual use. No single invention accomplished that change on its own.

1. The microprocessor (1971)
Intel’s 4004 is described by the Computer History Museum as the first “computer on a chip.” Its importance was not that it contained every part of a modern computer, but that it concentrated key computing functions in a small component. That made it practical to put computing into a wider range of products, rather than relying only on large or centralized systems. The 4004 was an enabling milestone, not the sole origin of personal computing. Computer History Museum: Intel 4004
2. Personal computing (1973 and the later 1970s)
“The first personal computer” depends on what counts as personal, what counts as a computer, and whether the milestone is an announcement, a launch or the creation of a market. York University’s Computer Museum says the MCM/70 was announced in Toronto in 1973 and was designed specifically for personal use. In the United States, the Smithsonian identifies the Altair 8800 as the machine that launched the personal-computer industry. It also notes the TRS-80’s consumer usability and the Apple II’s part in the sales growth of the late 1970s. These are distinct milestones, not a single uncontested first.

Information became easier to carry and share
Removable storage let people move data between systems, while email and network research changed how computers could communicate. These developments are related, but email, the internet and the later World Wide Web are not interchangeable terms.
3. The floppy disk (early 1970s)
A Computer History Museum storage timeline records a floppy disk loading mainframe data in 1971. The disk’s contribution was removable, portable data storage: information could be carried and loaded rather than remaining fixed in one system. Early floppy disks were large-format media; they should not be confused with the smaller formats that came later. Computer History Museum: Memory & Storage timeline

4. Email (1971)
The U.S. Department of State associates the first email with Ray Tomlinson in 1971. His use of the “@” symbol separated a recipient’s name from the location of the account, a convention that became familiar in email addresses. This was a landmark in networked communication, not the invention of the internet itself. U.S. Department of State: Communications Technology

In 1973, the U.S. Department of State dates the start of a DARPA research project concerned with connecting networks. The work around packet networking and TCP/IP helped establish a way for different networks to communicate, laying groundwork for later internet infrastructure. It did not mean that today’s Web, with its websites and browsers, already existed in the 1970s. U.S. Department of State: Communications Technology
Communication and location technology began long development arcs
Two technologies now associated with everyday mobile devices had important 1970s milestones, but neither was a finished, broadly available consumer service during the decade.
6. The handheld cellphone prototype (1973)
The Department of State dates Martin Cooper’s first publicized call on a handheld mobile phone to April 3, 1973. That was a prototype milestone; commercial handheld availability followed ten years later. The distinction matters: a successful demonstration showed what might be possible, not that consumers could already buy and use the modern cellphone service familiar today. U.S. Department of State: Communications Technology
7. GPS development (1973–1993)
The U.S. Department of State identifies GPS as a Defense Department development spanning 1973 to 1993. The 1970s therefore belong to the system’s development history, not to the era of a completed consumer navigation service. The familiar ability to get directions from a phone depends on later development and deployment beyond the decade. U.S. Department of State: Communications Technology

Home entertainment became more personal
Recording television at home and taking recorded music along changed when and where people could watch or listen. Both shifts depended on consumer products, rather than only on research or technical prototypes.

8. The home videocassette recorder
Sony’s corporate history records the 1970s launch of Betamax for consumer use. A home VCR made it possible to record television and watch recorded programs at a different time, loosening the tie between a broadcast schedule and a viewer’s schedule. Video formats and adoption histories varied, so the Betamax launch is best understood as a significant product milestone rather than the whole story of home video. Sony: Corporate History
9. The portable cassette player and Walkman (1979)
Sony dates the launch of the Walkman TPS-L2 portable stereo cassette player to 1979. It helped popularize listening to recorded music on the move, with headphones and a device carried by the listener. That is different from claiming it invented portable audio: the stronger, supported point is its role in making personal portable listening a prominent consumer experience. Sony: Corporate History
What connects these inventions?
The twelve milestones do not form a single chain in which one invention inevitably produced the next. Taken together, they show several directions of change: computing functions became compact enough to embed in products; personal computers brought computing closer to individual users; networking connected systems; removable media made information portable; and consumer electronics let people choose when and where to communicate or enjoy entertainment. Some of these changes began as research or prototypes, and others reached consumers as products. Their influence on modern life grew through later systems, commercialization and adoption—not all at once in the 1970s.
