He went on to host The Jon Stewart Show and then You Wrote It, You Watch It, both on MTV. Stewart has also appeared in several films, such as Big Daddy (1999) and Death to Smoochy (2002), but did few cinematic projects after becoming host of The Daily Show in 1999. He was also a writer and co-executive producer of the show. After Stewart joined, The Daily Show steadily gained popularity and critical acclaim, and during his tenure, it won 22 Primetime Emmy Awards, and was also nominated for news and journalism awards. 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. Since leaving The Daily Show, Stewart has for the most part maintained a low profile, with his sustained advocacy for 9/11 first responders being a notable exception.
