Teletype Corporation - this page is a stub

Teletype Corporation, abbreviated Teletype, was an American manufacturer of teleptypewriters, also known as telex machines, based in Skokie (Illinois, USA). The company was founded in 1928 after renaming the Morkrum-Kleinschmidt Company — itself established in 1902 — to the name of its trademark equipment: Teletype. The company was part of Western Electric (WE) and was merged into AT&T in 1930. Nevertheless it remained an independent operation. After AT&T was split-up in 1982, Teletype was gradually wound down and was finally dissolved in 1990 [1].


The company is well-known for its range of 5-level (ITA-2) teleprinters (telex machines) and associated peripherals, that were used worldwide by telecom providers like AT&T Bell. In the 1960s and 70s the company also produced a range of 8-level ASCII (ITA-5) teleprinters that were used as input/output terminals for the first generations of mainframe and mini computers.

Although Teletype was a registered trademark, it is often used as a generic expression for tele­typewriters and teleprinters. In modern computer operating systems, such as Unix and Linux, simple (virtual) terminal access to the command line — typically via serial or network port — is commonly referred to as the TTY protocol or the TTY port.
