Fast food has been around in the U.S. since the rise of establishments like White Castle in the 1920s. It has changed not only what and how we eat, but the worldwide supply chain, politics, pop culture and more.   Georgetown History professor Marcia Chatelain explores this in her Pulitzer Prize-winning book, “Franchise: The Golden Arches in Black America” and in her One Day University lecture, “Drive-Thru America.” She joins host Steven Schragis to discuss how America came to be the fast food nation.
