Executives of The WB network say they are not canceling 7th Heaven because of poor ratings -- it is their second highest-rated show behind Gilmore Girls, according to the Associated Press -- but because it costs too much. Speaking in Pasadena at the annual TV critics' winter press tour, WB Chairman Garth Ancier remarked that the series loses $16 million a year. "As much as we all love the show, we do have to run a business," Ancier said. The network's overall ratings are reportedly down by double-digit percentages this season.
