The groups behind a push to get the U.S. Federal Trade Commission to investigate YouTube’s alleged violation of children’s privacy law, COPPA, have today submitted a new letter to the FTC that lays out the appropriate sanctions the groups want the FTC to now take. The letter comes shortly after news broke that the FTC was in the final stages of its probe into YouTube’s business practices regarding this matter. They’re joined in pressing the FTC to act by COPPA co-author, Senator Ed Markey, who penned a letter of his own, which was also submitted today. The groups’ formal complaint with the FTC was filed back in April 2018.
