Universal Music Group (has logo with just "Universal Music Group")
UMG's history, traced back to as early as 1898: http://www.universalmusic.com/company/history
This is the current name of the holding company that was called PolyGram until 1998. It is owned by Vivendi. Its history is very complex, with many mergers, acquisitions, renamings and sell-offs. For instance, UMG owns the various branches of Mercury and Island Records.
