The telectroscope was the first prototype television system. The word telectroscope was also used to describe imaginary systems of distant seeing.

Real and imaginary telectroscope

The term telectroscope was used by the French editor Louis Figuier to popularize an invention he wrongly interpreted as real ^[1] and ascribed to Alexander Graham Bell. Figuier was probably misled by the article 'The Electroscope' published in The New York Sun of 29 March 1877. Curiously, the article signed 'Electrician' described as almost real a system whose operation resembled that of the World Wide Web some 125 years later. The system was reported to have just been invented by "an eminent scientist of the city'. The vivid description added inspiration to the research in the area which took off following the discovery of photoconductivity in selenium. Actually, the fake 'electroscope' described in the article had nothing to do with the real electroscope and it had never existed.

Nevertheless the word 'telectroscope' was widely accepted. It was used to describe the work of nineteenth century inventors and scientists such as Constantin Senlecq ^{[2] [3]} , George R. Carey ^{[4] [5]}, Adriano de Paiva ^[6] , and later Jan Szczepanik, whose experiments ^{[7] [8] [9]} fascinated Mark Twain ^{[10] [11]} . Both the hoax 'electroscope' of 1877 and Mark Twain's fictional telectroscope had an important effect on the public. They also provided feedback to the research.

Neither the fictional nor the real nineteenth century prototype telectroscopes were real television systems. Even after the invention of the scanning disk by Paul Nipkow the prototype telectroscopes did not ensure the satisfactory quality of image transmission. However, the telectroscope was an advanced research achievement that provided the solid basis for modern television and interactive multimedia.

'Telectroscope' was eventually replaced by the term 'television' most probably coined by Constantin Perskyi in 1900.
