The film industry rarely involves film anymore. The cameras and microphones use sensors. They translate the images and sounds into bits and bytes. Directors and editors manipulate the raw footage on computers, rather than with light boxes and scissors. Finished “films” get distributed as large files rather than as giant spools. Analog has given way to digital.
Although the film industry has witnessed many technological changes—the introduction of sound, of color, the invention of television—digitalization, more than any of these others, has unleashed a radical transformation of the industry. It has changed not just the nature of production, but also the businesses of distribution and of exhibition. It has challenged decades-long industry rules and routines. (from Introduction)
