Ever since the first black and white TV image was displayed, both developers and viewers
sought ways to make it better: to add more resolution, to increase the contrast ratio, and to be
able to faithfully replicate the color spectrum. An obvious yardstick to measure the progress
and quality of television has been cinematic film, which for years has been capable of
providing high-resolution moving images. Imagine a TV developer in 1939 who watched the
cinematic premiere of The Wizard of Oz or Gone with the Wind.
