The document describes a successful music programming promotion called "Leni Gagga" conducted by German radio station BB RADIO. It introduced Leni Gagga as the youngest head of music to address low listener perception that the station was not playing the best current hits. Over six weeks, Leni Gagga engaged listeners through on-air segments, social media interactions, and a final live event. The promotion was highly successful, improving the station's image for current hits and boosting listener interaction at a low cost. It became one of BB RADIO's most effective promotions ever and strengthened its brand.
