TTY stands for "TeleTYpe" or "TeleTYpewriter", and is also known as [[Teleprinter]] or Teletype.
RTTY stands for [[Radioteletype]]; [[character set]]s such as [[Baudot code]], which predated ASCII, were used. According to a chapter in the "RTTY Handbook", text images have been sent via teletypewriter as early as 1923.<ref name="rttyhb">{{cite book| last= Green| first= Wayne| title= RTTY Handbook| publisher = G/L Tab Books| location = [[Blue Ridge Summit, Pennsylvania]]| date= June 1972| isbn= 0-8306-2597-6}}</ref> However, none of the "old" RTTY art has been discovered yet. What is known is that text images appeared frequently on radioteletype in the 1960s and the 1970s.<ref name="joanstark"/><ref>
