Ad-friendly online video destination Hulu.com is drawing attractive demographics, according to a new study from Solutions Research Group. The average age of a Hulu user is 32, 10 years younger than the average online American, the study found. About two-thirds of users are male and 51% of users are between 12 and 29. The income of Hulu users is 22% higher than the U.S. average. Hulu users are also more likely to own laptops, smart phones and video-capable mp3 players. About 39% of Hulu users said they "frequently paid attention to ads seen online." The site does have a ways to go before it becomes a household name: only 15 percent of online Americans have even heard of Hulu.
