Fullscreen (aspect ratio)

Full screen or fullscreen refers to the 4:3 (1.33:1) aspect ratio of early standard television screens and computer monitors. The 4:3 aspect ratio became the standard in film because it mirrored film stock and was the easiest to use. Widescreen ratios started to become more popular in the 1990s and 2000s.
