Before revision: Background In 2009, the National Institute of Standards and Technology (NIST) issued a scientific paper stating that in addition to the typical white light brightness rating of display devices, there was a need for providing "an equivalent measurement that will better describe a projector's color performance when rendering full color imagery".NIST paper NISTIR 6657, January 2009: "A Rational Methodology for Estimating the Luminous Flux Based upon Color Primaries from Digital Projection Displays"'' In 2010, over 8.5 million projectors were purchased.Pacific Media Associates Press Release, March 24, 2011: Pacific Media Predicts Unit Shipments of Projectors Will Grow 35 Percent Per Year Through 2015 Although image quality consistently ranked at the top of purchase criteria, there was no standardized way to measure the color performance in displays, which is a key aspect of image quality, until the release of the Color Light Output specification .
