There's an excellent article https://en.wikipedia.org/wiki/Vocalion_Records
  about Aeolian Vocalion records; being sold to Brunswick, being 
licensed to Warner Bros., to the American Record Company, then purchased 
by CBS...eventually landing with EMI.

The vaults of Universal Music Group (500,000 pre-tape and tape items), 
EMI/Capitol (250,000 pre-tape and tape items) and PolyGram (275,000 
pre-tape and tape items), have also been greatly updated are also held 
now at modern, hi-tech storage facilities.

These three companies' holdings form more of a mosaic of both their 
older core labels and the absorbed catalogues of smaller companies they 
have bought.

Their older labels, such as Universal's Vocalion (1922) (shared with 
Sony) and Decca (1934), EMI's Capitol (1942) and Polygram's Mercury 
(1947) are also fairly intact. Polygram's vault, by the way, holds the 
catalogue of more acquired companies--with more than 70 labels--than any 
other major.
