This became known as Academy Standard and had an aspect ratio of 1.37:1.
Television adopted the Academy Standard to a 1.33:1 aspect ratio. This is the
recognized video standard commonly referred to as a 4:3 frame aspect ratio.
In 1953 Hollywood introduced the widescreen format for motion pictures in
an effort to pry audiences away from their television sets. Today, widescreen
?¬?lm has two standardized ratios: Academy Flat (1.85:1) and Anamorphic Scope
(2.35:1). High-de?¬?nition (HD) television adopted Academy Flat and has an
aspect ratio of 1.78:1. This is referred to as a 16:9 aspect ratio (Figure 2.2).
