Although the first modern projector was created in the 1870s, this now-ubiquitous piece of office equipment is a relatively recent addition to the workplace. Overhead projectors only began to be widely used in schools and businesses in the late 1950s and early 1960s, and the first CRT data projectors were released in the 1970s. Although they projected impressively smooth movements, they were bulky—weighing more than 40 pounds—and created distorted images. The 1990s saw the development of the multimedia projector, and in 1996, the first wireless projectors and DLP (Digital Light Processing) projectors made it to market. By 2010, the inclusion of DLP chips in projectors was a widespread practice, enabling the use of 3D technology by institutions that previously could not afford it, such as schools.
Today, overhead projectors remain a vital resource throughout the professional and educational worlds. Businesses and schools can choose from a wide range of brands—such as Epson, Panasonic and Optoma—and an even larger selection of features. The image-distortion issues of yesteryear are long gone, with sophisticated manual controls allowing users to fine-tune output and correct distortions and inconsistencies.
