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 .
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.
