"The Jazz Singer" had its European sound premiere at the Piccadilly Theatre in London on September 27, 1928. According to film historian Rachael Low, "Many in the industry realized at once that a change to sound production was inevitable." On January 16, 1929, the first European feature film with a synchronized vocal performance and recorded score premiered: the German production "Ich küsse Ihre Hand, Madame" ("I Kiss Your Hand, Madame"). Dialogueless, it contains only a few songs performed by Richard Tauber. The movie was made with the sound-on-film system controlled by the German-Dutch firm Tobis, corporate heirs to the Tri-Ergon concern. With an eye toward commanding the emerging European market for sound film, Tobis entered into a compact with its chief competitor, Klangfilm, a joint subsidiary of Germany's two leading electrical manufacturers. Early in 1929, Tobis and Klangfilm began comarketing their recording and playback technologies. As ERPI began to wire theaters around Europe, Tobis-Klangfilm claimed that the Western Electric system infringed on the Tri-Ergon patents, stalling the introduction of American technology in many places. Just as RCA had entered the movie business to maximize its recording system's value, Tobis also established its own production operations.
