80 Micro was a home computing magazine published by CWC/I publications (Wayne Green) between 1980 and 1988 about the TRS-80 microcomputer built by Tandy Corporation and sold through Radio Shack. The magazine featured program listings for the machine, primarily written in BASIC and occasionally Z80 assembly language. These programs were printed in the magazine, but could be purchased on cassette tape and diskette media under the name Load 80 to save some typing. The magazine also featured articles, letters, reviews and humor (including - from January 1980 through July 1983 - the monthly Kitchen Table International satire/parody column).
Starting out under the name "80 Microcomputing", the magazine was renamed to "80 Micro" on its 30th issue. Founded by Byte magazine founder Wayne Green, it was later sold to CW Communications. Green attributed the magazine's success to Radio Shack's policy of not allowing other companies to distribute their products through their stores, while other stores would not carry the products as Radio Shack customers did not frequent them. Thus 80 Micro became the most accessible venue for small companies to advertise in. Tandy also prohibited the Radio Shack stores it owned from selling or displaying 80 Micro to not lose sales to the magazine's advertisers, and Green—who claimed that most stores kept a copy hidden from "company spies"—asked readers to persuade franchise and other non Tandy-owned stores to sell the magazine.
In 1982, 80 Micro was the third largest magazine in terms of obtaining advertising, selling 152,000 issues. Programming contests for young children were featured annually, and were endorsed by both the Scholastic Corporation and the Boy Scouts of America.
