The match between England and Italy is in line to be the most-watched quarter-final game in the competition's history, organisers UEFA said on Wednesday.
European football's governing body said that according to figures submitted from the first 20 markets, 100 million viewers worldwide watched Sunday's match with more than 100 broadcasters still to report.
An average of 20.3 million people watched the game on the BBC in Britain, which was the highest quarter-final audience since Euro 2004 when 20.7 million people watched England lose to Portugal.
That match is the benchmark for the most watched quarter-final in the tournament's history as its total audience was 228.2 million.
