 In addition, cinema and variety theatre development had begun in the area with conversion of part of the exhibition space on the west side.In 1925 the Ufa-Palast am Zoo opened in one of these spaces, then Germany's largest cinema, followed in 1926 by the Gloria-Palast on the western side, where "The Blue Angel" premièred on 1 April 1930.By 1928, when Joseph Goebbels made a speech attacking the commercial establishments surrounding the Kaiser Wilhelm Memorial Church, the square contained a cluster of Berlin's premier cinemas—Ufa-Palast am Zoo, Gloria-Palast, Capitol, Marmorhaus and Tauntzien-Palast—in addition to cafés, theatres, and other business establishments, and some businessmen had sought to establish it as Berlin's Broadway.
