Children’s online privacy is not just for tweens and half-pints anymore. Companies are increasingly blocking targeted advertising to teen users in response to demanding state laws in Texas, Maryland, Colorado, Connecticut and several others that are designed to protect minors up to age 18. Additionally, the FTC began 2025 by adding multiple new hurdles and friction points for companies that collect the data of children under 13 by amending its Children’s Online Privacy Protection Act Rule (Amended Rule) for the first time since 2013. The first article in this three-part series discussed the key pacesetter laws that emerged in 2024 to regulate minors’ online activities and examined the most significant trends shaping this increasingly difficult compliance area. Part two addressed the new legal framework around minors’ privacy, spotlighted the Amended Rule’s most significant changes and examined their impact on companies’ compliance. The third article provided practical compliance considerations for businesses around requirements common to multiple laws, discussed a unified approach to protecting a vulnerable group and offered sources for guidance.
