The QVC home-shopping channel has agreed to pay $7.5 million to settle complaints by the Federal Trade Commission that it presented deceptive ads for dietary weight-loss supplements. QVC, a unit of John Malone's Liberty Media, had previously been charged with airing similar programs that included what the FTC charged were false and unsubstantiated claims for such products. At the time, the matter was settled when QVC agreed not to air them again. The new settlement further bars QVC from selling any products claiming to eliminate cellulite. QVC has been struggling during the current economic turndown and has been the principal drain on Liberty Media's profits. Last month it reported a 22-percent plunge in operating income during the fourth quarter of 2008.
