The Short Version
Eurovision's verified 2025 audience of roughly 166 million viewers — measured across only 37 public-service media markets — falls far short of substantiating a claim to be the world's most-watched non-sporting live event. Several historic non-sporting broadcasts, including major royal funerals and the Apollo 11 moon landing, are widely reported to have drawn audiences exceeding one billion. No authoritative source confirms Eurovision holds this global superlative, and the EBU's own figures are regionally scoped, not worldwide totals.
