The Network Advertising Initiative (NAI) is a cooperative of online marketing and analytics companies committed to building consumer awareness and establishing responsible business and data management practices. Many large advertising networks are members of the NAI. The NAI has developed a tool that allows consumers to opt out of targeted advertising delivered by NAI members' ad networks. To learn more about opting out of targeted advertising or to use the tool, visit www.networkadvertising.org.
