In 1977 three consumer-oriented personal computers appeared almost simultaneously: the Apple II, Tandy/Radio Shack's TRS-80, and the Commodore PET. It was the year personal computing stopped being a hobbyist kit and became an accessible consumer product. The IBM PC (1981) and the Apple Macintosh (1984) would expand the market massively. The personal computer moved computing from institutions, governments, and large corporations toward individuals, homes, schools, and small organizations, democratizing access to computing in a way comparable to what Gutenberg's press did for the written text.
