On CNN's AC360 program last night, Anderson Cooper was promoting "live webcasts" with news anchor Erica Hill, which would run during on-air commercial breaks. As explained here, the idea is that CNN viewers can go "behind the scenes" to continue their AC360 experience by watching the live stream on their computers. I dutifully did this and watched Hill and Cooper somewhat mindlessly chatting/flirting for several minutes. But wait: if CNN is urging on-air viewers to turn their attention to these "webcasts" during commercial breaks, then that means that CNN is diverting attention from its own on-air advertisers. That undermines CNN's all-important advertiser value proposition. That of course begs the question: is CNN's ad sales team on board with these webcasts? And if so, what are they thinking??
