looney tunes

In the early 1950s, Warner Bros. sold its black-and-white Looney Tunes (plus the first Merrie Melody, Lady, Play Your Mandolin!, and the B&W Merrie Melodies made after Harman and Ising left) to Sunset Productions. Warner insisted that the opening and closing titles be changed to remove all references to Warner Bros. The cartoons were distributed by Guild Films until it was sold to Motion Pictures for Television. In the 1960s, Seven Arts Productions bought that company. In 1967, Seven Arts merged with Warner Bros. to create Warner Bros.-Seven Arts thus putting those films back in Warner's ownership.[12]
In 1957, Associated Artists Productions (a.a.p.) acquired for television most of Warner Bros.' pre-1950[13][14] library, including all Merrie Melodies (except for those sold to Sunset) and color Looney Tunes shorts that were released prior to August 1948. Unlike the sale to Sunset Productions, a.a.p. was allowed to keep the Warner titles intact and simply inserted an "Associated Artists Productions presents" title at the head of each reel so each Merrie Melodie cartoon had the song "Merrily We Roll Along" playing twice[15] (while each Looney Tune had both opening songs each playing once[16]).[17] a.a.p. was later sold to United Artists, who merged the company into its television division—United Artists Television.
In 1981, UA was sold to Metro-Goldwyn-Mayer, and five years later, Ted Turner acquired the MGM library—which also included U.S. rights to the RKO Pictures library, in addition to its own pre-1986 material, the classic Warner Bros. library, and some of UA's own product, in an attempt to take over MGM. Turner's company, Turner Broadcasting System (whose Turner Entertainment division oversaw the film library), merged with Time Warner in 1996, thus the classic library was once again under ownership of WB (although technically they are owned by Turner, with WB handling sales and distribution).
All the while, starting in 1967 WB was able to retain the rights to "Lady Play Your Mandolin" and the black-and-white Looney Tunes, even though a number of them fell into the public domain (WB holds the original film elements)—a majority of these public domain shorts have been released on many low-budget independent home video labels. As of 2006, all WB's animated output (including the post-'48 shorts WB also kept) are under the same Time Warner umbrella of ownership.
UA (under the pre-WB/Turner-merger management of MGM/UA Home Video) officially released numerous compilations of the classic pre-8/48 cartoons on VHS and LaserDisc, most of these under the title The Golden Age of Looney Tunes. Today, Warner Home Video holds the video rights to the entire Looney Tunes/Merrie Melodies animated output by virtue of WB's ownership of Turner Entertainment—this is why their Looney Tunes Golden Collection DVD box sets include cartoons from both the pre-8/48 Turner-owned and post-7/48 WB owned periods.
