Looney Tunes is an American animated comedy series produced by Warner Bros. from 1930 to 1969 during the golden age of American animation alongside its sister series Merrie Melodies. It is known for introducing Bugs Bunny, Daffy Duck, Porky Pig, Elmer Fudd, Wile E. Coyote, Road Runner, Sylvester, Tweety, Yosemite Sam, Foghorn Leghorn, Marvin the Martian, Pepé Le Pew, Speedy Gonzales, Tasmanian Devil, Granny, and many other characters. After Bugs Bunny became the breakout recurring star of Merrie Melodies, and Looney Tunes went to color in the early 1940s, the two series gradually lost their distinctions and shorts were assigned to each series more randomly.
