CINEMA 21 was the largest cinema network in Indonesia, which has spread across the archipelago. Before Cinema XXI’s establishment, Cinema 21 controlled the overall market share of Indonesian moviegoers with varying ticket prices applied and the types of films shown, in accordance with the location and the intended target.

After Cinema XXI was established, slowly Cinema 21 turned into second-class cinema network, with most of the films are local movies and foreign films that are not playing at the Cinema XXI anymore. However, this condition does not apply in smaller cities outside Jakarta which don’t have any Cinema XXI theaters and where there are not many Cinema 21 theaters available.

In general, most CINEMA 21 studios are equipped with Dolby Digital sound systems, and even some of those are THX certified such as Hollywood KC (now Hollywood XXI), Karawaci and Mega (now Pluit Village XXI) in Jakarta. Not only that, some Cinema 21 even adapted the atmosphere and comfort equivalent to Cinema XXI. But again, it is based on the targeted market share and the agreement with the shopping center management.

Along with the demands of the times, 21 Cineplex has conducted a number of improvements and innovations, among which are to form a network movie theater into 3 separate brands, namely Cinema 21, Cinema XXI and The Premiere to target different markets. This movie network spread across several major cities throughout the archipelago and most of them located in shopping centers with Hollywood and Indonesian movies as the main menu, equipped with Dolby Digital and THX sound system. Recently, some cinemas are now equipped with Dolby Atmos, IMAX, and IMAX with Laser.
