(Anna Moneymaker | The New York Times) Joseph Simons, chairman of the Federal Trade Commission, speaks at a news conference at the agency's headquarters in Washington, on Wednesday, Sept. 4, 2019. As part of a settlement with the FTC and New York’s attorney general, Google agreed to pay a record $170 million fine and to make changes to protect children’s privacy on YouTube, as regulators said the video site had knowingly and illegally harvested personal information from youngsters and used that data to profit by targeting them with ads.
