Warner Bros. Animation in the context of "Warner Bros. Pictures Animation"

Isadore "Friz" Freleng (/ˈfriːləŋ/ FREE-ləng; August 21, 1905 – May 26, 1995), credited as I. Freleng early in his career, was an American animator, cartoonist, director, producer, and composer known for his work at Warner Bros. Cartoons on the Looney Tunes and Merrie Melodies series of cartoons from the 1930s to the early 1960s. In total he created more than 300 cartoons.

He introduced and/or developed several of the studio's biggest stars, including Bugs Bunny, Porky Pig, Tweety, Sylvester, Yosemite Sam (to whom he was said to bear more than a passing resemblance), Granny, and Speedy Gonzales. The senior director at Warners' Termite Terrace studio, Freleng directed more cartoons than any other director in the studio (a total of 266), and is also the most officially-honored of the Warner directors, having won five Academy Awards and three Emmy Awards. After Warner closed down the animation studio in 1963, Freleng and business partner David H. DePatie founded DePatie–Freleng Enterprises, which produced cartoons (including The Pink Panther Show), feature film title sequences, and Saturday-morning cartoons. After the company's dissolution in 1981, Freleng joined Warner Bros. relaunched animation division and produced several Looney Tunes one-off specials and compilation films.

Warner Bros. Cartoons, Inc. was an American animation studio, serving as the in-house animation division of Warner Bros. during the Golden Age of American animation. One of the most successful animation studios in American media history, it was primarily responsible for the Looney Tunes and Merrie Melodies series of animated short films. The characters featured in these cartoons, including Bugs Bunny, Daffy Duck, and Porky Pig, are among the most famous and recognizable characters in the world. Many of the creative staff members at the studio, including directors and animators such as Chuck Jones, Friz Freleng, Robert McKimson, Tex Avery, Robert Clampett, Arthur Davis, and Frank Tashlin, are considered major figures in the art and history of traditional animation. Warner Bros. Cartoons was founded in 1933 by Leon Schlesinger as Leon Schlesinger Productions.

Schlesinger sold the studio to Warner Bros. in 1944, after which the Warner Bros. Cartoons name was adopted. The studio closed in 1963, and Looney Tunes and Merrie Melodies were subsequently subcontracted to Freleng's DePatie–Freleng Enterprises studio from 1964 to 1967. Warner Bros. Cartoons re-opened that year, under Warner Bros.-Seven Arts, before closing again in 1969. It was succeeded by Warner Bros. Animation, which was established in 1980.

Merrie Melodies is an American animated comedy short film series distributed by Warner Bros. Pictures. It was part of the Looney Tunes franchise and featured many of the same characters. Originally running from August 2, 1931, to September 20, 1969 (during the golden age of American animation), it was revived in 1979 with new shorts being sporadically released until June 13, 1997. Merrie Melodies originally placed emphasis on one-shot color films in comparison to the black-and-white Looney Tunes films. After Bugs Bunny became the breakout character of Merrie Melodies and Looney Tunes transitioned to color production in the early 1940s, the two series gradually lost their distinctions and shorts were assigned to each series randomly.

Merrie Melodies was originally produced by Harman–Ising Pictures from 1931 to 1933 and 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. It was outsourced to DePatie–Freleng Enterprises and Format Productions from 1964 to 1967, and Warner Bros.-Seven Arts Animation resumed production for its final two years of the golden age era. When the series was revived in 1979, DePatie–Freleng produced new shorts briefly, but they were replaced by Chuck Jones Productions the following year. During its final years, the series was produced by Warner Bros. Animation.
