After Warner Bros. Records opened regional markets in Australia, Canada, France, Germany, Japan, and the United Kingdom, US copyright laws forced it to change its name outside the US to first Kinney Music in 1971, and then WEA Records in 1972.
Throughout most of the 1970s the company had been content to release records on its constituent labels - Warner Brothers, Elektra and Asylum. In 1978, WEA started a label which bore the corporate name.
