The OSA became law on 26 October 2023, with a phased approach to implementation, overseen by Ofcom. The OSA makes online service providers that allow users to share content or interact with each other, and search services, legally responsible for keeping people, especially children, safe online. This includes social media services, online marketplaces, review services, discussion forums and gaming services. Ofcom’s initial analysis suggests that more than 100,000 online services could be subject to these new rules.
