Young men are the most frequent online video viewers, but US Internet users of all ages are getting into the act.

That is the main finding of BurstMedia’s “Online Insights” report, conducted in December 2007.

70% of users surveyed had viewed online video content. A majority of all age segments had watched online videos, including more than half of respondents age 65 and older.

Young men were viewing most often. More than a third of the 18-to-24-year-old male online video viewers in the survey reported that they watched once a day or more.
