While the online video metrics between Comscore and Compete rarely agree, they almost matched for YouTube in December according to a post in NewTeeVee.
Could that mean, at least, as afar as YouTube is concerned, the audiences being measured by both metrics services are similar? 29,884,593 uniques (Compete) vs. 29,597,000 (Comscore).
Not bad. Maybe now, the online metrics for the rest of the chart can agree (ie: Yahoo Video has 4,137,147 on Compete but 21,611,000 on Comscore).
