During the Opening Ceremonies of the olympics; the athletes from Greece enter first, in honor of the original Olympics held in Greece. Then the other athletes follow by nation in alphabetical order (except for the Beijing 2008 Games where it was based on the number of characters in the country's name). The host country's athletes always come last. After the games are announced as "officially open", this is followed by the raising of the Olympic Flag. The torch ceremony then begins. The running of the torch usually begins weeks before the Olympic ceremony, transporting the Olympic torch to each country that lies between Greece and the host country. The most exciting moment of the Olympic Opening Ceremony is when the torch enters the stadium and is lights the Olympic Flame. The Flame is always kept burning until the end of the Olympic Games.
