Entertainment One, a.k.a. eOne Music, is the primary label music division of Entertainment One Ltd. Once started as a record and video shop in Toronto, where their main offices are still located, Entertainment One grew to become a main multi-media player. Besides continuously releasing recordings on the Entertainment One record label, they along the way also acquired other labels and companies, the most important being the US division of Koch Records (in 2005). That company was renamed E1 Music and the deal also marked their big-scale entering the US market.
