3.4 million people tuned in from all over the world to watch the Italian tenor perform his Music for Hope concert live from an empty Milan Cathedral on Easter Sunday.
The Music for Hope performance is also available on YouTube and has been watched more than 24 million times so far.
Accompanied by an organist, Bocelli sang four songs inside the magnificent Duomo di Milano and ended with a rendition of Amazing Grace from the cathedral steps with a montage of images showing the empty streets of Paris, London and New York.
"On the day in which we celebrate the trust in a life that triumphs, I'm honoured and happy to answer 'Si' to the invitation of the City and the Duomo of Milan," the visually impaired star said in a message played before the short concert.
"Thanks to music, streamed live, bringing together millions of clasped hands everywhere in the world, we will hug this wounded Earth's pulsing heart," he said.
