In 2005, Massenburg was replaced by Sylvia Rhone, former CEO of Elektra Records. Motown was merged with Universal Records to create the Universal Motown Records and placed under the newly created umbrella division of Universal Motown Republic Group. Motown began celebrating its fiftieth anniversary (January 12, 2009) in late 2008, including the release of a The Complete No. 1's box set containing Motown #1 hits from Billboard's pop, R&B, and disco charts, reissues of classic-era Motown albums on CD, and other planned events, which were released in collaboration with Universal Music Group's catalog division Universal Music Enterprises.
