Welcome to Ad Age's Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. What people are talking about today: The outcry over Facebook, political data firm Cambridge Analytica and their handling of user data isn't going away, and there's a steady stream of developments keeping it in the news. (If you're still catching up on this story, start with this look at the whistleblower, via Ad Age's Simon Dumenco.) Facebook founder Mark Zuckerberg hasn't said anything publicly about how Cambridge Analytica was able to harvest data from 50 million Facebook profiles. In fact, Zuckerberg's latest Facebook post dates back to March 2, when he was baking cookies for Purim.
Among the new headlines:
