Televoting, or voting by telephone, was first introduced at the Eurovision Song Contest 1997 as an alternative to the traditional jury system and was tested by five countries - the rest used the jury system. By 2004, all participating countries used this system. Since the 2009 finals, televoting now makes up 50% of a country's total score with the remaining 50% coming from a jury of five music professionals from each participating country which are then combined. The 50:50 system proved so successful that it was extended into the semi-finals for the 2010 contest and has remained in place ever since to not only determine the overall winner, but to also pick the ten qualifiers from each semi-final.
