In 1994 seven countries joined the Eurovision Song Contest in what was the biggest single expansion in participants since the contest began in 1956. Estonia, Hungary, Lithuania, Poland, Romania, Russia and Slovakia all competed in the 39th Eurovision Song Contest in Dublin. Poland's debut at the Eurovision Song Contest was very successful when their representative Edyta Gorniak finished second with 166 points. The interval act in 1994 was the then unknown Riverdance, an act which combined traditional Irish folk music with modern dance. Riverdance became a global phenomenon, with the exception of participating artists, it is arguably the biggest money-spinner ever created by Eurovision. Lithuania scored zero points with its first ever entry.
