The number of unique viewers of online video increased 5.2% year-over-year according to The Nielsen Company, from 137.4 million unique viewers in January 2009 to 142.7 million in January 2010.

The Nielsen Company today reported overall online video usage and top online brands ranked by video streams for December 2009. Year-over-year, unique viewers, total streams, streams per viewer and time per viewer were up, led by 13 percent growths in time per viewer.

More than 11 billion video streams were served up in the U.S. in the month of November, a 17% jump from the same time period last year.

Fall TV premieres, coupled with coverage of the presidential election and the financial crisis, boosted online video viewing at all four networks’ websites in September.
NBC.com, which grew 312% month-over-month, saw the largest September increase in video viewers, followed by FOX Broadcasting and ABC.com, with 165% and 105% growth, respectively, Nielsen Online reported Thursday.
