An interactive television system includes a central exchange and a plurality of consoles variously located at residences of viewers of TV programming. Each console includes a code reader capable of reading program codes, which are broadcasted with the TV signals of programs as unique identifiers thereof. A viewer, upon seeing a TV program of interest, actuates a button, and the console transmits to the central exchange an uniquely identifying console code together with the program code currently being read by the code reader. The central exchange then initiates a facsimile transmission or a datafile transmission of program data, retrieved from a database and associated with the received program code, to the console identified by the received console code.
