Descrizione:

By1971 Sam Fedida at the British Post Office and teams at the BBC and the IBA (Independent Broadcasting Association) have started developing Web-like information systems that use televisions for display. The two latter systems, based on work by Philips, broadcast data on an unused portion of the TV signal. They evolve into the Teletext information services found on most European TVs into the 2000s. Sam Fedida's videotex standard at the Post Office (which also runs the telephone system) uses phone lines, and has high ambitions for broad-reaching uses like today’s Web. It becomes the foundation of England’s Prestel and, later, France’s wildly successful Minitel.
