TTS
Teletypesetter. The TTS telegraphy code was introduced in 1928 to enable the Associated Press telegraphy network to distribute news articles in a format that did not require rekeyboarding to be typeset. TTS was input and output as 6-bit punched paper tape. TTS was the first commercially successful digital markup language/communication protocol that included code for presentation purposes. Most modern desktop publishing systems and word processors are based on fundamental software methods and concepts first commercialized in the newspaper publishing industry for use with TTS code.
