In the early days, extended information films were shown in cafes, teahouses and other places. With the progress and development of movies, there have been cinemas specially built for showing movies. The development of movies-from silent movies to stereoscopic movies, from black-and-white movies to color movies, from ordinary screens to wide screens to dome screens and circular screens-has greatly changed the shape, size, proportion and acoustic technology of cinemas. The cinema must meet the technical requirements of film screening and obtain the good visual and auditory effects it deserves.

Movie generation

The first generation cinema-before 1990s, it was represented by the old-fashioned cinema with single hall and single room.

The second generation cinema-1995 was located in the commercial district, represented by multi-hall and digital cinema. But it has not yet formed a real business circle format.

The third generation cinema-from 2000 to now, cinema has really become a format of modern commerce. Formally, it has been further upgraded on the basis of digital cinema. It can play its own movies, including 3D movies, and has relatively complete ancillary facilities.

The fourth generation cinema began to appear in the United States in 2008, and a micro-commercial complex with film city as the main body appeared. This is a brand-new movie experience that integrates leisure, entertainment, catering and shopping.
