Between 1977 and 1980 it was replaced by the Intervision Song Contest, which was still held in Sopot. Unlike the Eurovision Song Contest, the Sopot International Music Festival often changed its formulas to pick a winner and offered many different contests for its participants. For example, at the 4th Intervision Song Festival (held in Sopot August 20–23, 1980) two competitions were effective: one for artists representing television companies, the other for those representing record companies. In the first the jury considered the artistic merits of the songs entered; while in the second, it judged the performers' interpretation."
