Guests talked about the history of the Progressive Era, the Industrial Revolution, and labor practices at the turn of the century through the Writings of Upton Sinclair. Sinclair's The Jungle was published in 1906. Set in the Union Stockyards on the south side of Chicago during 1904-5, the novel's chief goal was to expose abusive labor conditions in the stockyards. However, in addition to doing this, the work received most of its notoriety from its descriptions of the filth of the processing plants and the ingredients of its processed meats. The book is considered by many as the final impetus for the passage later that year of the Pure Food and Drug Act and the Meat Inspection Act in the administration of President Theodore Roosevelt. It was Roosevelt who dubbed Sinclair and other writers in the time period who were exposing what they viewed as inequities in society as "Muckrakers." This program was telecast, in part, from a food processing facility in Chicago and highlighted current meat processing procedures as well as occupational safety issues.
