ESPN25 was a special event conducted to mark the 25th anniversary of ESPN. During the run-up to the anniversary date of September 7, 2004, the network counted down the top sports moments of the last 25 years (the "ESPN era"). Each Tuesday, a new 25-to-1 list was unveiled, as was the next headline in that 25-to-1 countdown. In addition, each day during SportsCenter, the next moment in the list of the top 100 moments of the ESPN era was shown. The celebration concluded by declaring the Miracle on Ice hockey game between the United States and the Soviet Union at the 1980 Winter Olympic Games the #1 moment, game, and headline of the last 25 years.
