On November 30, WilmerHale addressed key privacy issues in the mobile app environment as part of the firm's Cybersecurity, Privacy and Communications Practice Webinar Series. We discussed how to navigate the quickly developing regulatory and self-regulatory environment for advertising (including cross-device advertising), personalized content, and web and in-app analytics on mobile devices, based on guidance from and enforcement actions by key regulators, self-regulatory bodies and private enforcement. The session focused on FTC, FCC and State AG policy and enforcement; filling the gaps: self-regulatory guidelines from the Digital Advertising Alliance, Network Advertising Initiative and Mobile Marketing Association; private litigation: TCPA cases and lessons learned; and key differences in the EU and APEC.
