CBS, NBC, News Corp. and others have launched TV Watch, an online campaign to push the V-chip/TV ratings system, reports B&C
. "Spring Clean Your TV" is a promo video and Web site for parents to
help them vet the content their children see. "Studies show that the time children spend watching television increases 150% this time of year," said TV Watch Executive Director Jim Dyke, announcing
the campaign. TV Watch was created as a response for more federal regulation of media.
