Fifty years ago, 45 million people—the largest crowd to ever witness a football game—tuned in to a match-up that would forever change the face of American sports. According to former Philadelphia Inquirer columnist and bestselling author of Black Hawk Down, Mark Bowden, it was the perfect confluence of great players, great coaches, new tactics—and the omnipresence of television—ushering in the modern era of American football.

Mark Bowden will also be appearing and signing books in the Philadelphia Inquirer tent, Booth D, on Sunday, May 18 from 2:30 to 3:30 p.m.
