There's a series on the History Channel that I've been enjoying, The Food That Built America. Standard documentary style of recreations and "experts" giving opinions, it tells of the American food rivalries from the late 1800's until now. Kraft, McDonald's, Pizza Hut, Frito's, Coca-Cola, etc. I've learned a few things about the companies and founders that I thought was interesting. So many started out on a shoestring to later became the corporate behemoths that we know now.
