Video Viewership

Emily Steel has a solid article in today's Wall Street Journal about the audience for online TV shows. While Nielsen has traditionally measured TV viewership, there are several companies measuring online watchers, they use different techniques -- and they haven't finalized how to measure streaming video.

Industry insiders suggest that until measurement improves, online video won't grow as much as it might otherwise. And so it goes with advertising. As a step in that direction, Nielsen recently announced that it would merge its offline and online measurements.
