Bonnie Fuller, the Canadian mother-of-four who defined both the celebrity weekly and the celebrity magazine editor, is to leave her job. As the demanding editor of Us Weekly, Fuller was the most sought-after executive in the magazine industry; but she traded in her reputation for a richer deal at David Pecker's American Media. Fuller did improve group flagship Star, but it wasn't enough to dislodge Us Weekly, which continued to thrive under Fuller's successor, Janice Min. It became apparent that the peppy formula was stronger than the personal magic which Fuller had sold to American Media's Pecker. Marginalized at her new employer, Fuller spent her last couple of years in increasingly bizarre efforts to promote Star and her own flagging brand, appearing on game shows such as Identity (see screencap) and damning in blog posts the trashy celebrity culture that she had done so much to promote. It was a brutal fall from grace; and now Fuller cannot even claim to be seeking a quieter life. Her book, The Joys of Much Too Much, extolled the virtues of a hectic but full career and home life, over the simplicity and tranquility from which she will now suffer.
