Which of the following options shows the correct chronological order of communication technologies ?
Telegraph, Movie Camera, Radio, Television
Date each technology and then read the sequence off.
Telegraph is the earliest by a wide margin. Morse demonstrated the electric telegraph in the late 1830s and the first long-distance line opened in 1844, making it the pioneering electrical medium of the nineteenth century.
Movie camera comes next. Practical motion-picture cameras appeared in the 1890s, with the Lumière brothers' public projection in 1895 marking the start of cinema.
Radio follows. Marconi's wireless telegraphy experiments ran from the mid-1890s, but radio as a medium carrying sound to an audience arrived with regular broadcasting from around 1920.
Television is last. Baird's mechanical demonstration came in 1926 and regular electronic broadcasting began in the 1930s.
Placing them in order gives Telegraph, Movie Camera, Radio, Television. The useful anchor is that radio precedes television, since sound broadcasting was established a decade before pictures joined it.
Hence the correct chronological order is Telegraph, Movie Camera, Radio, Television.
