ABC had nine out of the top ten most viewed television series for the month of February according to Nielsen VideoCensus. ABC's online video player is regularly derided as having one of the worst (if not the worst) video players on the Internet. The quality of the video is fine (outstanding, actually) but there are a slew of other issues with the player. No matter, as obviously people will suffer through that in order to get the content they want.
Lost was number on with 2.5 million unique viewers, up 41% over January. Lost also ranked number one in total streams with 48 million, up 20% from January. Dancing with the Stars (1.5 million unique viewers), Grey's Anatomy (1.3 million unique viewers), The Bachelor (962,000 unique viewers), Brothers & Sisters (801,000 unique viewers), Desperate Housewives (793,000 unique viewers) and Scrubs (655,000 unique viewers) followed Lost, ranking 2nd, 3rd, 4th, 5th, 6th and 7th, respectively.
 It's worth noting that Nielsen Videocensus does not currently measure Hulu (it does measure NBC.com though) so in terms or rankings there is a big slice that is not covered.
