Tom and Jerry is an American animated series of short films created in 1940 by William Hanna and Joseph Barbera. It centers on a rivalry between its two main characters, Tom Cat and Jerry Mouse, and many recurring characters, based around slapstick comedy. Tom and Jerry has gained a worldwide audience and is one of the most popular and critically acclaimed cartoon series. In its original run, Hanna and Barbera produced 114 Tom and Jerry shorts for Metro-Goldwyn-Mayer from 1940 to 1957. During this time, they won seven Academy Awards for Animated Short Film, tying for first place with Walt Disney's Silly Symphonies with the most awards in the category. After the MGM cartoon studio closed in 1957, MGM revived the series with Gene Deitch directing an additional 13 Tom and Jerry shorts for Rembrandt Films from 1961 to 1962. Tom and Jerry then became the highest-grossing film series of all time, overtaking Looney Tunes. Chuck Jones then produced another 34 shorts with Sib-Tower 12 Productions between 1963 and 1967. Two more shorts were produced, The Mansion Cat in 2001 and The Karate Guard in 2005, for a total of 163 shorts. Various shorts have been released for home media since the 1990s. A number of spin-offs have been made, including the television series The Tom and Jerry Show (1975–77), The Tom and Jerry Comedy Show (1980–82), Tom & Jerry Kids (1990–94), Tom and Jerry Tales (2006–08), and The Tom and Jerry Show (2014). The first feature-length film based on the series, Tom and Jerry: The Movie, was released in 1992 before ten direct-to-video films were produced between 2002 and 2013. Numerous Tom and Jerry shorts have been subject to controversy, mainly over racial stereotypes which involves the portrayal of the recurring black character Mammy Two Shoes and characters appearing in blackface. Other controversial themes include cannibalism and the glamorization of smoking.
