Stewart is known as an outspoken , humorous critic of personality-driven media shows , in particular those of the U.S. media broadcast networks such as CNN , Fox News , and MSNBC . Critics say Stewart benefits from a double standard : he critiques other news shows from the safe , removed position of his " news satire " desk ; Stewart asserts that neither his show nor Comedy Central purport to be anything other than satire and comedy . In spite of its self-professed entertainment mandate , '' The Daily Show '' has been nominated for news and journalism awards among its accolades . Stewart hosted the 78th and 80th Academy Awards . He is the co-author of '' America ( The Book ) : A Citizen 's Guide to Democracy Inaction '' , which was one of the best-selling books in the U.S. in 2004 , and '' Earth ( The Book ) : A Visitor 's Guide to the Human Race '' , released in 2010
