Screwed-up starlets, already the heart of a pretty unpleasant economy of voyeurism, are becoming a regular gift to newspaper ad sales too. Today's New York Daily News includes a full-page ad screaming "Don't Die Britney!" to promote the Canterbury Institute, which offers medical treatment for addiction. "While the rest of the world is going in and out of rehab," the ad copy reads, "Canterbury Institute has changed the rules of addiction treatment forever." The ad, created by Jugular in New York, is a sequel to Canterbury's "Don't Die Lindsay!" ad from last month.
