Founded in 2000, the Network Advertising Initiative (NAI) is the leading self-regulatory association exclusively focused on third-party advertising online and in mobile. With nearly 100 members, just about every Internet ad served in the US involves the technology of one or more NAI companies. These third-party services are crucial for a diverse Internet ecosystem and digital economy as they help to facilitate the dynamic, free, ad-supported Internet that consumers love and expect. But privacy and consumer trust are also crucial. The NAI's role, therefore, is to ensure the health of the online ecosystem by maintaining and enforcing high standards for data collection and use in interest-based advertising on desktop, mobile, and beyond. With buy-in and support from our member companies, the NAI sets the bar for consumer privacy through a body of self-regulatory policies – the NAI Code – and through a robust compliance enforcement program that helps members live up to our high standards, but holds them accountable when they don't.
