Expo 2000 was a World Expo held in Hanover, Germany from 1 June to 31 October 2000. It was located on the Hanover Fairground, which is the largest exhibition ground in the world. Initially, some 40 million people were expected to attend the exhibition over the course of months; however, eventually with less than half of this number, the Expo was a flop and turned out to be a financial failure.
