The Cricket World Cup is the international championship for One Day International cricket organized by the International Cricket Council every four years. The tournament involves preliminary qualification rounds leading to a final tournament and is considered one of the world's most viewed sporting events. The first men's Cricket World Cup was held in England in 1975, just four years after the first ODI match, though women's and earlier multi-team tournaments have been held. Hosting of the tournament has rotated between ICC members since 1987.
