What is known is the fact that text images appeared frequently on radio teletype in the 1960s and the 1970s. However, none of the "old" RTTY art has been discovered yet. According to a chapter in the "RTTY Handbook", text images have been sent via teletypewriter as early as 1923. TTY stands for TeleTYpe/TeleTYpewriter and is also known as Teleprinter or Teletype. Other examples were found from the Ancient Romans where the Roman characters were used to form an image. Also, to mark divisions between different print jobs from different users, bulk printers often used ASCII art to print large banners, making the division easier to spot so that the results could be more easily separated by a computer operator or clerk.Ĭreating pictures from letters and writing symbols dates back to Ancient Egypt. One of the main reasons ASCII art was born was because early printers often lacked graphics ability and thus characters were used in place of graphic marks. "Studies in Perception I" by Ken Knowlton and Leon Harmon from 1966 shows some examples of their early ASCII art. Most examples of ASCII art require a fixed-width font (non-proportional fonts, like on a traditional typewriter) such as Courier for presentation.ĪSCII art had been originally developed around 1966, by computer-art pioneer Kenneth Knowlton, who was working for Bell Labs at the time. ASCII art can be created with any text editor, and is often used with free-form languages. The term is also loosely used to refer to text based art in general. ASCII art is an artistic medium that relies primarily on computers for presentation and consists of pictures pieced together from the 95 printable (from a total of 128) characters defined by the ASCII Standard from 1967 and ASCII compliant character sets with proprietary extended characters (beyond the 128 characters of standard 7-bit ASCII).
