The Great British Bake Off attracted an average of 10.4 million viewers as it returned for a seventh series - a record opener for the BBC One show.
The episode was watched by 47.5% of all television viewers with a peak audience of 11.2 million at 20:50 BST.
That means it beat the most-watched moments of the Rio Olympics, which peaked at 11.1 million viewers.
Judge Paul Hollywood said the show was going "back to basics" this year, with critics praising its winning recipe.
Twelve new bakers were seen entering the Bake Off tent on Wednesday, tackling drizzle cakes, Jaffa cakes and a genoise sponge.
