You've noticed the name on the AmEx card commercials like have, right? Ever wondered who CF Frost is? The answer is not too exciting, but here it is courtesy of The Straight Dope :
Charles Frost--or Chuck, as we like to call him--is
a real person. He was an account executive for
the advertising firm of Ogilvy & Mather, which put together the
original "Do you know me?" ads for American Express.
I wonder if American Express could have capitalized on this somehow; I bet that they could have. Why is it that the first answer isn't on their site? They could have built a legend, built a story, built a contest around eagle-eyed people that noticed the name on the card.
