Sillerman has taken control of the company through CKX, which also owns Elvis Presley's name, image, films and the Graceland museum. It has paid £64.5m in cash and 1.87m shares to acquire 19 Entertainment, with a further £19.2m to be paid after results are delivered for the year ending June 30 2005.
The deal will see Fuller taking a role as a director of CKX as well as continuing to control 19 Entertainment, where he plans to continue world domination of popular culture.
"CKX will provide 19 with a powerful platform for global growth and allow us to fully take advantage of all the amazing opportunities that lie ahead," Fuller said.
His company, founded in 1985, is behind artists such as the Spice Girls, Annie Lennox, S Club 7 and former 'American Idol' participants such as Kelly Clarkson and Clay Aiken.
It also has deals with Victoria and David Beckham and owns the 'Pop Idol' franchise, which is now in use in more than 30 territories, including the fantastically successful 'American Idol'.
Sillerman said: "As we grow our business, the content that 19 owns, controls, is developing or develops in the future will become important elements in our effort to refocus the relationship between the creators of content and the distributors of that content."
