Who has won the most ICC ODI World Cups?

The first three editions of the tournament from 1975 to 1983 were officially called the Prudential World Cup, with matches being played over 60 overs per innings, in traditional white clothing, red cricket balls, and during the day. 

The eight nations that participated in the inaugural ODI World Cup tournament included Australia, England, East Africa, India, New Zealand, Pakistan, Sri Lanka, and the West Indies, with the team from the Caribbean defeating Australia by 17 runs in the final. 

India and Pakistan hosted the 1987 ODI World Cup, the first tournament outside of England, with overs being reduced from 60 to 50 per inning. 

The 1992 World Cup saw day/night matches and fielding restrictions introduced in Australia and New Zealand, with traditional garb replaced with colour clothing and red balls with white. Additionally, South Africa was allowed to play following decades of international isolation due to apartheid. 

Sri Lanka became the first host nation to win the ICC Cricket World Cup in 1996, although Pakistan was the venue for the final. India achieved the same feat in 2011 but became the first nation to win a home final, with Australia and England replicating India's performance in 2015 and 2019,  respectively. 

In 2011, the ICC introduced the DRS system at the ODI World Cup in India, which has become a staple in all formats of cricket.

The typical format of an ODI World Cup used in recent tournaments involves a group stage, where a team plays a set number of fixtures against other teams in the group, with the top four teams making it to the knockout stage, which consists of semi-finals, and the final. 

In case of a tie between teams in any knockout match or the final, a Super Over will decide the winner, as was the case in 2019 when England defeated New Zealand in a Super Over.
