There have been a great number of anamorphic format trade names, for reasons of prestige, technology, or vanity.
The basic 35 mm anamorphic format originally popularized as CinemaScope has been known by a number of other monikers.
In recent decades, it has generally been considered a cliché throwback, and thus the generic name of anamorphic format has become predominant.
All of the following trade names refer to the modern SMPTE-standard anamorphic 35 mm format or what was regarded as the standard at that time.
The term anamorphic should not be considered synonymous with widescreen; VistaVision was non-anamorphic, and at the time of shooting, so was Techniscope .
