How can companies employ interest-based online advertising – targeting the exact consumers they covet – without running afoul of data privacy laws?  During a recent panel at PLI’s Sixteenth Annual Institute on Privacy and Data Security Law, Julia Horwitz, coordinator of the Electronic Privacy Information Center’s Open Government Program and Noga Rosenthal, general counsel and vice president for compliance and policy for the Network Advertising Initiative, offered their perspectives on the current interest-based advertising (IBA) climate.  The panelists discussed the evolution of IBA, potential privacy pitfalls and how companies are self-regulating.
