The Bundesvision Song Contest (often shortened BSC or BuViSoCo) was a song competition held annually between the sixteen states of Germany. Created by German entertainer Stefan Raab and aired live on ProSieben, the show was loosely based on the Eurovision Song Contest, with slightly different rules aiming at promoting German-language music by requiring that at least 50% of each song's lyrics were performed in German.
