Is YouTube collecting data on our kids?

In a formal complaint, child advocates and consumer groups are asking the Federal Trade Commission to investigate and impose potentially billions of dollars of penalties on Google for allegedly violating children's online privacy and allowing ads to target them. The privacy of millions of children around the world who visit YouTube, to watch cartoons, nursery rhymes, science experiments or videos of toys being unboxed, may be compromised. YouTube's business model relies on tracking IP addresses, search history, device identifiers, location and other personal data about its users so that it can gauge their interests and tailor advertising to them. The model isn't supposed to work for US children, who are protected by the Children's Online Privacy Protection Act. However, advocacy groups believe, that Google is violating that law.
