Polydor is a record label owned by Universal Music Group, headquartered in the United Kingdom. Polydor was originally an independent branch of the Deutsche Grammophon Gesellschaft. Its name was first used as an export label in 1924, the British and German branches of the Gramophone Company having... severed their ties during World War I. Deutsche Grammophon claimed the rights to the His Master's Voice trademark for Germany, where HMV recordings were released under the Electrola trademark. In turn, DGG records exported out of Germany were released on the Polydor label. Polydor became a popular music label in 1946 while Deutsche Grammophon became a classical music label. The German rights to the His Master's Voice trademark was sold by Deutsche Grammophon to the Electrola Records unit of EMI in 1949. Polydor remained Deutsche Grammophon's export label, including classical music, in France and the Spanish-speaking world for the remainder of the long-playing era, as a result of language and cultural concerns. In the early 1960s orchestra leader Bert Kaempfert signed unknowns Tony Sheridan and the Beat Brothers - who would later become famous as The Beatles - to Polydor.

Warner Bros. Records Inc. is an American record label. It was the foundation label of the present-day Warner Music Group, and now operates as a wholly owned subsidiary of that corporation. It maintains a close relationship with its former parent, Warner Bros. Pictures, although the two companies... are independently owned. Rob Cavallo currently serves as Chairman of the company. Warner Bros. Records was originally established in 1958 as the recorded music division of the American movie studio Warner Bros. Pictures. For most of its existence it was one of a group of labels owned and operated by larger parent corporations. The sequence of companies that controlled Warner Bros. and its allied labels evolved through a convoluted series of corporate mergers and acquisitions from the early 1960s to the early 2000s. Over this period, Warner Bros. Records grew from a struggling minor player in the industry to become one of the top recording labels in the world. In 2003 these music assets were divested by their then owner Time Warner and purchased by a private equity group. This independent company traded as the Warner Music Group , before being bought by Access Industries in 2011.
