Before YouTube can become a truly effective platform for ad delivery it will have to work to make sure only U.S. audiences are served U.S. ads according to BusinessWeek.
The comments on the potential stumbling block come from Podtrac CEO Mark McCrery. He feels that advertisers won't be interested in paying for audience reach that is outside the U.S. Based on numbers from comScore about 23 percent of YouTube's audience comes from the U.S. The site will have to find a way to break those viewers out and segment them in order for advertisers to feel comfortable on the site.
