SCOOP was a teletext magazine for teenagers, available at ten high schools in USA, 1985. It was broadcasted on WGBH-TV in Boston using the NABTS/NAPLPS standards, which included the alpha-mosaic features of the French Antiope standard (see page 12).
“The kind of information presented (topical subjects, sports scores, around town information, etc.), the way it was presented (short, tightly edited segments), and the format (contemporary, graphic-heavy, easy to access) were appropriate to a teenage audience.”
