Warner Bros.-Seven Arts

Warner Bros.-Seven Arts was formed in 1967 and became defunct in 1970, when Seven Arts Productions acquired Jack Warner's controlling interest in Warner Bros. for $32 million and merged with it. The deal also included Warner Bros. Records, Reprise Records and the B&W Looney Tunes library (plus the first Merrie Melodie, Lady, Play Your Mandolin!). Later that same year, Warner Bros.-Seven Arts purchased Atlantic Records. Head of production was Kenneth Hyman, son of Seven Arts co-founded Eliot Hyman.

History
Warner Bros.-Seven Arts was acquired in 1969 by Kinney National Company, (which had also acquired National Periodicol Publications, later known as DC Comics ) who proceeded to delete "Seven Arts" from the company name, reestablishing it as Warner Bros. Due to a financial scandal over its parking operations, Kinney National spun off its non-entertainment assets in 1971 (as National Kinney Corporation) and changed its name to Warner Communications Inc. which has since merged with Time, Inc. to form Time Warner.

Sound Effects
The sound effects used in the W7 cartoons were very unusual. Using very small amount of Hanna-Barbera and WB/Looney Tunes sound effects (mostly rarely used sound effects) for some reasons. Mainly because due to the limitations and budget at that time. The film editors were both Hal Geer and Donald A. Douglas (who was also a film editor at Hanna-Barbera Productions).

Most of the cartoons except Norman Normal (1968) used the sound effects. One cartoon The Great Carrot Train Robbery (1969) was very limited and lacking on the sound effects.
