Earlier this week, California Gov. Jerry Brown approved the Social Media Disclose Act, to take effect in 2020.  We previously blogged about the Social Media DISCLOSE Act, which will place new disclosure obligations on social networks like Facebook and Twitter; advertising platforms like Google; and anyone who engages in online political advertising.  Covered platforms in particular should start thinking now about how they will comply with the law, or else risk being caught flat-footed when it kicks in just in time for the 2020 state elections.
