In this systematic critique of the structural basis of U.S. media -- arguably the first one ever published -- Upton Sinclair writes that "American journalism is a class institution serving the rich and spurning the poor." Likening journalists to prostitutes, the title of the book refers to a chit that was issued to patrons of urban brothels of the era.
Fueled by mounting disdain for newspapers run by business tycoons and conservative editors, Sinclair self-published The Brass Check in the years after The Jungle had made him a household name. Despite Sinclair's claim that this was his most important book, it was dismissed by critics and shunned by reviewers. Yet it sold over 150,000 copies and enjoyed numerous printings.
