CORE Media Group, formerly CKX, Inc., was an American company founded on February 7, 2005 that owned and developed entertainment content and intellectual property.

The "C" and "K" in "CKX" stood for "Content is King", representing the focus of the company's business strategy to acquire established content, and then to improve, enhance and develop the marketing of such content. The "X" takes the initial of founder Robert F.X. Sillerman. This is a trademark of many Sillerman companies, such as "SFX Entertainment" and "FXM Asset Management"

Before its founding in 2005, and during a period from 1986 to August 2002, the company operated a franchise of golf equipment, formerly known as Sports Entertainment Enterprises. In August 2002 the company sold all of its former assets. From September 2002 to February 2005, the company's main priority was to pursue a transaction with a business enterprise.

As a result, it began building a stake in the image rights of boxer Muhammad Ali. In 2005, it bought British company 19 Entertainment from Simon Fuller, who subsequently joined the company's board. With the purchase, the company acquired a majority share of the rights to the Idol series, including American Idol and So You Think You Can Dance, as well as Pop Idol in Great Britain and numerous other international versions. Later that year it bought an entertainment agency, with artists on its roster such as Robin Williams, Billy Crystal and Woody Allen. In 2005, the company bought 85% of the rights to the name, image and likeness of Elvis Presley, and the operations of Graceland, from the trust of Lisa Marie Presley.

In 2007, Fuller and Sillerman launched a takeover bid for CKX, valuing it at $1.3bn or $13.75 per share, but their attempt failed due to its timing coinciding with the start of the Global Credit Crunch.
