Ted Turner, Gerry Lenfest and the late Bill Daniels are among the cable industry entrepreneurs who massed great fortunes and opted to give away the bulk to charity. Each of these three has donated more than $1 billion to various groups. "So many of the cable industry's leaders have been so generous over the years in so many ways," Cable Center CEO Larry Satkowiak said. "I would say their generosity rivals the Fords and the Carnegies -- those people who created the great foundations of the past. They have all found things to support that are important to them and that they are passionate about."
