Last month, Nielsen reported that the popular video site had 8.9 million unique users for the month, while comScore reported a much higher 42 million for the same period. For April, the numbers get even crazier. Nielsen says viewers watched 373 million video streams, but at the same time showed a big decline in unique viewers, moving to 7.4 million for the period. Quantcast however, another online measurement provider, says they see no evidence of a decline in unique viewership.
Says Hulu of the Nielsen numbers: "There is work to be done."
The problem however, is in the fact that online measurement is still an unreliable science which can adversely affect advertising decisions.
