Home cinema, also called home theater, are entertainment systems that seek to reproduce movie theater quality video and audio in a private home. In the 1950s, home movies became popular in the United States with Kodak 8 mm film projector equipment becoming affordable. The development of multi-channel audio systems and laserdisc in the 1980s created a new paradigm for home cinema. In the early to mid 1990s, a typical home cinema would have a Laserdisc or S-VHS videocassette player fed to a large rear projection television. In the late 1990s, home theatre technology progressed with the development of DVD, Dolby Digital 5.1-channel audio, and High-Definition Television.
