T. Trini, Di videotape in videotappa, note sui primi esperimenti televisivi da parte degli artisti, in “Domus”, Milano, n. 495, febbraio
The article describes Gerry Schum’s TV pieces. It mentions the exhibition “Gennaio 70” (Bologna 1970) curated by Trini himself, Renato Barilli and Maurizio Calvesi and “Telemuseo” “a video-theatre” in the context of the exhibition “Eurodomus 3” for which videotapes were made by Fabio Mauri, Gianni Colombo, Gino Marotta, Vincenzo Agnetti, Trini himself and others.
Trini also says that Ginafranco Baruchello was one of the first pioneer of videotape but soon gave this medium up because of its poor quality. pdf here
