Some info (French) from Collection Minitel
The CNET rather pushes its investigations towards the coupling of telephone and television, developing, in 1974, the TIC-TAC system (Integrated Terminal Including Television and Keyboard Call). But TIC-TAC is only a prefiguration. The culmination of the work, a veritable marriage of computers and the telephone, will take the name of Interactive Videotex.
