Programmatic video and TV are both taking off, but lots of challenges still remain. What are they, how will they be resolved and over what time frame? These were the key questions addressed in our closing session at the SHIFT // Programmatic Video & TV Ad Summit a few weeks ago. The session included Joanne Chen (Partner, Foundation Capital), Barry Green (Head of Business Development, North America, VertaMedia), Dave Katz (VP/GM, Programmatic Revenue Platforms & Operations, Univision), Rich Sobel (SVP, Programs & Services, Publicis Media) and Joe Grover (CEO, Altitude Digital) moderating.
