Tandy Corporation announced the TRS-80, one of the world's first mass-produced personal computers.

Tandy Corporation was an American family-owned retailer based in Fort Worth, Texas that made leather goods, operated the RadioShack chain, and later built personal computers.

The TRS-80 Micro Computer System is a desktop microcomputer developed by American company Tandy Corporation and sold through their Radio Shack stores. Launched in 1977, it is one of the earliest mass-produced and mass-marketed retail home computers. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor], referring to its Zilog Z80 8-bit microprocessor.

A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people.
