The document evaluates two potential sources for credibility on the topic of responsible marketing to children. The first source is from the Mars company website and discusses their policies around responsibly marketing candy and food brands to children. The second source is a statement from a commissioner at the Federal Communications Commission regarding protecting children from excessive television advertisements. The FCC statement provides more credibility as it is from a regulatory body and discusses congressional obligations to protect children, while the Mars source discusses their own internal policies from the perspective of the company. The FCC source would be considered more credible for research on this topic.
