On September 15, Governor Newsom signed the California Age-Appropriate Design Code Act (ADCA) into law. The bill – which is modeled after the UK ICO’s code of practice for age-appropriate design – will impose broad new requirements on businesses that provide an online service, product, or feature that is “likely to be accessed by children.” The law will require significant operational changes for any company subject to its requirements. Joan Stewart and Tyler Bridegan of Wiley are joined by Emily Jones of UK-headquartered international law firm Simmons & Simmons to discuss the ADCA and lessons U.S. businesses can learn from the UK Code.
