Wikipedia
CinemaScope is an anamorphic lens series used, from 1953 to 1967, for shooting widescreen movies. Its creation in 1953 by Spyros P. Skouras, the president of 20th Century Fox, marked the beginning of the modern anamorphic format in both principal photography and movie projection.
The anamorphic lenses theoretically allowed the process to create an image of up to a 2.66:1 aspect ratio, almost twice as wide as the previously common Academy format's 1.37:1 ratio. Although the CinemaScope lens system was made obsolete by new technological developments, primarily advanced by Panavision, the CinemaScope anamorphic format has continued to this day. In film-industry jargon, the shortened form, 'Scope, is still widely used by both filmmakers and projectionists, although today it generally refers to any 2.35:1, 2.39:1, or 2.40:1 presentation or, sometimes, the use of anamorphic lensing or projection in particular. Bausch & Lomb won a 1954 Oscar for its development of the CinemaScope lens.
