three formats of international cricket. Australia and India have won the tournament twice each (India's 2002 win was shared with Sri Lanka due to the final being washed out twice), while South Africa, New Zealand, Sri Lanka (shared with India), West Indies and Pakistan have won it once each. No non-full member team has ever crossed the first round of the Champions Trophy. Format Up to 2006 the Champions Trophy was held every two years. The tournament had been scheduled to be held in Pakistan in 2008 but was moved to South Africa in 2009 due to security reasons. From then on it has been held every four years like the World Cup. The Champions Trophy differs from the World Cup in a number of ways. The matches in the Champions Trophy are held over a period of around two and a half weeks, while the World Cup can last for over a month. The number of teams in the Champions Trophy are less than the World Cup, with the latest edition of the World Cup having 10 teams whereas the 2017 ICC Champions Trophy had 8 teams. For 2002 and 2004, twelve teams played a round-robin tournament in four pools of three, with the top team in each pool moving forward to the semi-final. A team would play only four games (two in the pool, semi-final and final) to win the tournament. The format used in the Knock Out tournaments differed from the formats used in the Champions Trophy. The competition was a straight knock out, with no pools and the loser in each game being eliminated. Only eight games were played in 1998, and 10 games in 2000. Since 2006, eight teams have played in two pools of four in a round-robin format, with the top two teams in each pool playing in the semi-finals. Losing a single match potentially means elimination from the tournament. A total of 15 matches are played in the present format of the tournament, with the tournament lasting about two and a half weeks.
