Weingarten is a face-to-face philanthropist

Explore, his branch of the $1.6 billion Annenberg Foundation, gives away millions of dollars every year, but Weingarten doesn't accept grant proposals or give money from a distance. He spends time with people whose causes he believes in and films the visits to call attention to what they do.

"I can't understand giving if it's impersonal," Weingarten says. "I don't give grants by somebody sending a 20-page docket."
