ALBANY, N.Y. — Companies that operate popular kids websites like nickjr.com and barbie.com agreed to a $835,000 settlement and to change their practices after an investigation found the sites were enabled with technology that tracked kids’ internet activities.

New York Attorney General Eric Schneiderman announced his office reached settlements with Viacom (VIA), Mattel (MAT), Hasbro (HAS) and JumpStart Games after an investigation into the companies found violations of the Children’s Online Privacy Protection Act.

The investigation, called “Operation Child Tracker,” found that websites operated by the companies enabled third-party vendors, such as marketing and advertising companies, to track children’s online activity — which violated federal law.

The companies run websites associated with Nick Jr. and Nickelodeon owned by Viacom, as well as popular brands owned by Mattel and Hasbro — such as Barbie, Hot Wheels and American Girl.

“Federal law demands that children are off-limits to the prying eyes of advertisers,” Schneiderman said in a statement.

“Operation Child Tracker revealed that some of our nation’s biggest companies failed to protect kids’ privacy and shield them from illegal online tracking."

The agreement includes the fine and upgrades to the companies' websites.

Viacom will pay $500,000; Mattel will pay $250,000; and JumpStart will pay $85,000.

Hasbro will not pay a penalty because it is part of a "safe harbor program" through the Federal Trade Commission that already requires more disclosures of Web activity, Schneiderman said.

The companies said they will conduct regular scans to monitor for third-party tracking technology and take other measures to ensure their sites are safe, Schneiderman said.

The companies also will have to report their efforts to Schneiderman's office.

Federal law prohibits the unauthorized collection of children’s personal information on websites aimed at children under age 13.

Hasbro said it cooperated fully with New York's investigation and has taken steps to improve its websites.

"Moving forward, we will be more closely vetting and monitoring companies that work on our behalf," the company said in a statement.

"We are rolling out a new, stricter online privacy protection policy for our partners and enacting new protocols and technology to scan our digital properties for any cookies, widgets or other applications that may violate our policy."
