Nielsen Analytics says broadband video is the hot space for ad revenue right now. From ClickZ:
The study, conducted in partnership with Scarborough Research, suggests that broadband video actually extends the reach of traditional television and provides a perfect place to target advertising to a “young, affluent, highly educated” consumer with round-the-clock access to high-speed Internet.
After years of worrying that online video would “cannibalize” their viewership, stations and networks are starting to get it. The more you put your stuff out there, the more people will watch.
