What is it?
This is a, I believe, 4-part series on the History Channel about men like Cornelius Vanderbilt, John D. Rockefeller, Andrew Carnegie, and J.P. Morgan. It's a narrated film that's almost like a movie that covers important events in the expansion of railroads, the oil industry, and the mass-production of steel; hence "the men who built America." The time span this show covers is the 1860s-1890s.
It's a really good show, and if you haven't seen it, you really should. For the people who may have seen it, what do you think?
