The Zomba Group of Companies (sometimes referred to as Zomba Music Group or just Zomba Group) was a music group and division currently owned and operated under Sony Music Entertainment. The division was renamed to Jive Label Group in 2009 and was placed under the RCA/Jive Label Group umbrella.Founded independently in the mid-seventies by Clive Calder and Ralph Simon, the group has had interests in music release, distribution, production, publishing, equipment rental, recording studios, and artist management. Though the financial structure and annual revenue of Zomba during the company''s independent period was probably only known to CEO Clive Calder (the company was registered privately offshore in the Dutch Antilles), Zomba was widely regarded as the most successful of the independent music companies.
