The nationwide class action suit that involved Google and Nickelodeon allegedly tracking our innocent, innocent children was largely defeated by the defending companies recently. The Court of Appeals for the Third Circuit felt that planting cookies on children's computers and devices didn't run afoul of both state and federal laws, at least not the ones the parents identified.
It wasn't a complete victory for Viacom, Nickelodeon's parent company, though. The federal court allowed one privacy claim against the entertainment company stand as it had collected children's information despite promises not to do so. It looks like completely fibbing parents still isn't kosher in corporate America.
