The majority of the 5,506 cinemas that existed in 1939 within the so-called Altreich (the "Old Reich", i.e., Germany without Austria and the Sudetenland) were small companies run by private owners. However, a large number of rules and regulations issued by the Reichsfilmkammer limited the entrepreneurial freedom of the cinemas considerably. For instance, it was mandatory to include a documentary and a newsreel in every film programme.
