ABSTRACT
The aspect ratio of film in the cinema was 4:3 (which can also be expressed as 1.33:1) dating back to the silent days. When television was invented, it took the same shape screen, and the proliferation of widescreen formats today dates back to the cinema’s attempt to win audiences away from television with a wider screen and colour in the first CinemaScope film, The Robe(aspect ratio 2.30:1) in 1953.
