Teaching Projection

Decline of film projectors
In 1999, digital cinema projectors were being tried out in some movie theatres. These early projectors played the movie stored on a server and played back through the projector. Due to their relatively low resolution (usually only 2K), the images at the time showed pixelization blocks in some scenes, much like images on early widescreen televisions. By 2006, the advent of much higher 4K resolution digital projection had removed any traces of pixelization. The systems became more compact than the larger machines of four years earlier. By 2009, movie theatres started replacing the film projectors with digital projectors. In 2013, it was estimated that 92% of movie theatres in the United States had converted to digital, with 8% still playing film. In 2015, numerous popular filmmakers—including Quentin Tarantino and Christopher Nolan—lobbied large studios to commit to purchase a minimum amount of 35 mm film from Kodak. The decision ensured that Kodak's 35mm film production would continue for several years.

High-resolution digital projectors offer many advantages over traditional film units. For example, digital projectors contain no moving parts except fans, can be operated remotely, and are relatively compact. They also allow for much easier, less expensive, and more reliable storage and distribution of content, including the ability to display live broadcasts.
