Last week I had the opportunity to moderate a second screen panel and attend several other panels and presentations at the Variety Entertainment App Summit in LA. While I greatly enjoyed the panel on second screen monetization with YuMe, Magic Ruby, Cinram/1K and MTV, I thought the most eye-opening session was the presentation of Microsoft Xbox SmartGlass by Mark Turner. While I had seen Ron Pessner present something similar back at a 2nd Screen Society in NY last June and I had been playing with the platform at home for the past 2 weeks (and even wrote about it last week), somehow the epiphany of just how big this could be for the entire second screen ecosystem had escaped me. Let me talk you through the key points they get me excited and explain why I spent this weekend re-exploring the platform at home.
