From the Toronto Sun:
Now that Nik Wallenda’s walk across Niagara Falls has come and gone, the city is beginning to digest just how big of an event it was.
Mayor Jim Diodati said ever since he heard of Wallenda’s proposal he knew the number of eyes on Niagara Falls would be astronomical.
“We were given a conservative estimate of 410 million (people),” he said.
On Saturday, Diodati revealed that Enigma Research Corp., the same company hired to track crowds for the Winter Festival of Lights and the Shaw Festival, estimated one billion people witnessed Wallenda’s walk.
“The potential for this was enormous and we achieved our full potential. The stars aligned perfectly,” Diodati said. “I think what we’ve effectively done is moved the falls from the back burner to the front burner on people’s to-do and bucket lists.”
