@syntax "London CS was created from Decca because Decca couldn’t use their own name in USA.
(There
was a small private label which was named Decca). To avoid any
problems, Decca decided right from the Start to create for USA a new
Name, London."
From Wikipedia, fountain of all knowledge:
Decca Records is a British
record label established in 1929 by
Edward Lewis. Its U.S. label was established in late 1934 by Lewis, along with American Decca's first president
Jack Kapp and later American Decca president
Milton Rackmil. In 1937, anticipating
Nazi aggression leading to
World War II, Lewis sold American Decca and the link between the UK and U.S. Decca labels was broken for several decades.
[1] The British label was renowned for its development of recording methods, while the American company developed the concept of
cast albums in the musical genre. Both wings are now part of the
Universal Music Group, which is owned by
Vivendi, a
media conglomerate headquartered in
Paris, France. The US Decca label was the foundation company that evolved into UMG.
