"Telling the truth's not easy, but in advertising it's the law. This year millions of us will be misled by deceptive advertisers promoting products and services that don't do what they promise."The organization asks members of the public to report a misleading ad by filing a complaint at TINA.org.
Truth in Advertising has a handy glossary page that defines regulatory agencies and laws, marketing practices, and topics under discussion. I've added the glossary to my page of marketing links, here.
