In the group's annual ranking based on companies' sponsorship of shows that are family-friendly vs. shows with sexual content, violence or profanity, rounding out the top 10 worst were: L'Oreal, Pepsi-Cola, GlaxoSmithKline, Reckitt Benckiser, Target, Kohl's, Verizon Communications and Toyota.
Those cited for sponsoring the best shows were Coca-Cola, Clorox, Century 21 Real Estate, H&R Block, Ferrero; CVS Caremark, Whirlpool Corp., Hershey, State Farm and Hewlett-Packard.
"The role that television advertisers play in determining what type of content comes into every home in America cannot be overstated," said PTC President Tim Winter. "We commend the advertisers on our best list that have chosen to associate their hard-earned corporate brands with positive programming that the entire family can watch together."
'Shocking and outrageous'
And the worst list? "Parents can thank many of the advertisers on the worst list for enabling the networks to pump some of the most shocking and outrageous content on the air today directly into their living rooms. Our top offenders include General Motors, which advertised on one of the most shocking episodes of Fox's 'Family Guy,' and Nissan, which helped pay for the bloodiest episode in the 'Dexter' series to air on broadcast television," he said.
"In the 2007-2008 TV season alone, these two advertisers showed up nearly 1,000 times on 'red light' shows that are unsuitable for children according to PTC's traffic light ratings system."
GM and Nissan couldn't immediately be reached for comment.
