Is advertising a soulless den of carnivorous capitalism? Yes. But that doesn't mean it can't occasionally accomplish a few good things. This week, Adweek's panel of editors looks at how marketers have tried to advance social causes, with mixed results. We also look at the week's best ads, the baffling chaos of White House communications, HBO's programming announcements and much more. This week's panel: • David Griner, Adweek Director of Digital Initiatives • Tim Nudd, Adweek Creative Editor • Kristina Monllos, Adweek Senior Editor, Brand Marketing • Chris Ariens, Adweek Media Editor
