Looney Tunes is a Warner Bros. animated cartoon series which ran in many movie theaters from 1930 to 1969. It preceded the Merrie Melodies series and is WB's first animated theatrical series. The regular Warner Bros. animation cast also became known as the "Looney Tunes" (often misspelled, intentionally or not, as "Looney Toons").
The name Looney Tunes is a variation on Silly Symphonies, the name of Walt Disney's concurrent series of music-based cartoon shorts. Looney Tunes originally showcased Warner-owned musical compositions through the adventures of cartoon characters such as Bosko and Buddy. Later Looney Tunes shorts featured popular characters such as Bugs Bunny, Daffy Duck, Porky Pig, Elmer Fudd, Sylvester, Tweety, Marvin the Martian, Taz, Wile E. Coyote and Road Runner, Foghorn Leghorn, Yosemite Sam, Pepé Le Pew, Speedy Gonzales, and many others. Originally produced by Harman-Ising Pictures, Looney Tunes were produced by Leon Schlesinger Productions from 1933 to 1944. Schlesinger sold his studio to Warner Bros. in 1944, and the newly renamed Warner Bros. Cartoons continued production until 1963.
Looney Tunes were outsourced to DePatie-Freleng Enterprises from 1964 to 1967, and Warner Bros. Cartoons re-assumed production for the series' final two years. From 1942 until 1969, Looney Tunes was the most popular short cartoon series in theaters, even exceeding Disney and other popular competitors.
