Social media and mobile apps provide consumers and companies with a host of benefits, such as improved access to information and the tailoring of content to the consumer, but also present privacy and security challenges that are continually evolving. At a recent PLI program, a panel of regulators shared their views on the emerging regulatory landscape for social media and mobile apps. Laura D. Berger, a senior attorney in the division of privacy and identity protection at the FTC; Joanne McNabb, the director of privacy education and policy in the privacy enforcement and protection unit of California’s Attorney General’s office; and Thomas M. Selman, executive vice president, regulatory policy, and legal compliance officer of FINRA, discussed their respective agencies’ roles and responsibilities, the enforcement priorities of their agencies, and examples of best practices in the use and development of social media and mobile apps. D. Reed Freeman, Jr., a partner at WilmerHale, moderated the panel.
