Disco was a pop music program that aired in Germany on the ZDF network from 1971 to 1982. It generally aired on the first Saturday of each month at 7:30PM, each show running 45 minutes. 133 shows were produced. The show was hosted by German actor and comedian Ilja Richter. Its lesser known predecessor on ZDF, 4-3-2-1 Hot & Sweet was aired between 1966 and 1970, presenters included Ilja Richter and Suzanne Doucet. Disco generally served a younger pop-oriented audience compared to ZDF's Hitparade, and until 1972, its main competitor was Beat-Club (originally patterned after the pure live-act show Ready Steady Go! in the UK, from the late-1960s turning more and more into psychedelic music videos made especially for the invited acts), followed by Musikladen, both on ARD.
