The Intervision Song Contest (ISC) was an international song contest for artists from countries of the former Soviet Union and members of the Shanghai Cooperation Organisation. It was previously the "Eastern Bloc equivalent to the Eurovision Song Contest". Its organiser was Intervision, the network of Eastern Bloc television stations. The contest would usually take place in the Forest Opera in Sopot, Poland. The ISC was organised between 1977 and 1980. It replaced the Sopot International Song Festival (Sopot ISF) that had been held in Sopot since 1961. In 1981 the ISC/Sopot ISF was cancelled because of the rise of the independent trade union movement, Solidarity, which was judged by other Eastern bloc communist governments to be "counter-revolutionary". A revived contest took place in 2008, though subsequent editions planned to stage the contest again in both 2014 and 2015 did not materialize. History The first Sopot International Song Festival was initiated and organised in 1961 by Władysław Szpilman, assisted by Szymon Zakrzewski from Polish Artists Management (PAGART). The first three editions were held in the Gdańsk Shipyard hall (1961–1963), after which the festival moved to the Forest Opera (Opera Lesna). The main prize has been Amber Nightingale through most of its history. 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 20–23 August 1980) two competitions were organized: one for artists representing television companies, the other for those representing record companies. In the first competition, the jury considered the artistic merits of the songs entered, while in the second, it judged the performers' interpretation. The festival has always been open to non-European acts, and countries like Cuba, Dominican Republic, Mongolia, New Zealand, Nigeria, Peru, South Africa and many others have been represented in this event. The contest lost popularity in Poland and abroad in the 1980s. The rather unconvincing organizations by TVP made the authorities of Sopot give the organization of the 2005 Sopot International Song Festival to a private TV channel, TVN. Since 1999, there has been no contest. TVP chose to invite well-known artists instead, featuring the likes of Whitney Houston or The Corrs. In 2005, TVN was expected to bring the competition
