TeleVideo Corporation was a United States company that achieved its peak of success in the early 1980s producing computer terminals. TeleVideo was founded in 1975 by K. Philip Hwang, a Utah State University, Hanyang University graduate born in South Korea [1] who had run a business producing CRT monitors for arcade games since 1975. The company was headquartered in San Jose, California.

A TeleVideo terminal model 925 made around 1982[2]

TeleVideo's terminal protocol was popular in the early days of microcomputers and was widely supported by applications as well as terminal emulators (often referred to as "TeleVideo 925 emulation").[3]

TeleVideo also built CP/M-compatible 8-bit desktop and portable personal computers based on the Z80 processor. Up to sixteen of these machines could be connected to proprietary multi-user systems through serial interfaces.[4] In April 1983, TeleVideo introduced an MS-DOS 2.0-compatible personal computer based on the Intel 8088. This was introduced as the Model TS-1603 and included 128 KB RAM (expandable up to 256 KB), integrated monitor, modem and keyboard. The Model TS-1603 ran both TeleVideo PC DOS 2.0 and CP/M-86 1.1.

The company later turned to manufacturing Windows-compatible thin client computers,[5] but eventually sold this business line to Neoware in October 2005.[6] The latter was subsequently taken over by Hewlett-Packard in 2007.[7]

On March 14, 2006, TeleVideo, Inc. filed a voluntary petition for reorganization under Chapter 11 of the United States Bankruptcy Code.[8][9]

After more than 35 years in business and with millions of terminals sold worldwide, TeleVideo discontinued the manufacturing and sales of all terminal products as of September 30, 2011.[10]
