The Center for Science in the Public Interest, the Boston-based Campaign for a Commercial-Free Childhood and two Massachusetts parents, Sherri Carlson of Wakefield and Andrew Leong of Brookline, have threatened to sue Kellogg Co. and Viacom Inc., should the companies fail to stop using characters such as Spongebob SquarePants to promote “sugar-filled” cereals. “As a parent, I do my best to get my kids to eat healthy foods. But then they turn on Nickelodeon and see all those enticing junk-food ads. Adding insult to injury, we enter the grocery store and see our beloved Nick characters plastered on all those junky snacks and cereals. This irresponsible marketing to young children undermines my efforts as a parent and must be stopped,” remarked plaintiff Carlson, a mother of three.
