The countdown clock date at the beginning of the video refers to the date on which the programme was copied, and the actual recording of the 51st IEE Faraday Lecture took place at City Hall, Cardiff, on 24/25th November 1975.

The lecture is presented by Howard Steel, Director of Engineering at IBA and Dr Boris Townsend. It begins with an overview of Michael Faraday's work, electric current and how this applies to broadcasting. There is a clip in the opening sequence from a 1936 early BBC programme to illustrate the long history of broadcasting. There is also a short clip of the Grand Place Clock Tower in France that was transmitted as the first cross-Channel television relay from the continent in 1950. The lecture is a combination of a presentation, graphics and film clips with demonstrations and models. The lecture covers 1) how does television work 2) how are television programmes made and transmitted and 3) what is new in television.

The lecture ends with information and a live demonstration of 'Oracle' a new invention of teletext that produces written information on the television as well as pictures. A demonstration shows that by adding teletext capability to television coupled with a telephone a television set can be turned in to a domestic computer terminal.
