1964–1969: DePatie–Freleng and Seven Arts era During the mid-late 1960s, the shorts were produced by DePatie–Freleng Enterprises (and Format Productions) (1964–1967) and Warner Bros.-Seven Arts (1967–1969) after Warner Bros. shut down their animation studio. The shorts from this era can be identified by their different title sequence, featuring stylized limited animation and graphics on a black background and a new arrangement, by William Lava, of "The Merry-Go-Round Broke Down" which had first been used in the 1963 experimental short "Now Hear This" directed by Chuck Jones.
