Environment Canada Weather Channel using the alphageometrical videotex protocol Telidon. From the mid 1980s. Thanks to Frederic Cambus for sharing.
Some teletext/videotex standards works with more than just alphanumerical characters. Like the Canadian Telidon, which used vector graphics. These are Telidon images, made by Jacques Palumbo in 1986.
Meanwhile in Japan, videotex was more complex: it was alphaphotographic. That is a combination of text and hi-res photos. It supposedly worked like a fax machine for the TV. Pic or it didn’t happen?
“Nancy Reagan Takes the Subway”, an interactive comic strip by Maria Manhattan produced at the Alternate Media Center at NYU in 1982 with the Norpak Telidon terminal.
Toxic Wastes from A to Z (coming after you and me) by John Fekner is a parody of a children’s alphabet learning aid which runs alphabetically through a list of toxic pollutants. Martin Nisenholtz invites John Fekner, Andy Warhol, Keith Haring and others to experiment with an early interactive computer graphics system (Telidon) at New York University’s Alternate Media Center (Interactive Telecommunications Program). Fekner received his first international award at Toronto’s Video Culture Festival in the Videotex category.
