The first HD movie experiments took place in the 1970s, using analog video formats such as 2-inch Quadruplex and 1-inch Type C. These early HD movies were primarily used for industrial and educational purposes, but they paved the way for future developments. In the 1980s, the introduction of digital video formats like CD-ROM and laserdisc enabled the creation of higher-quality HD movies. However, these early digital formats were expensive and limited in their distribution.
