The mobile video audience crossed 20 million for the first time in the first quarter of 2010, up 51.2% from a year ago, according to the latest Three Screen Report from Nielsen. That total is also up from the audience of 17.6 million in the fourth quarter of 2009, but still represents less than 10% of all U.S. mobile customers.

Time spent watching mobile video was flat over the last year, at an average of three hours, 37 minutes per viewer. Separately, Nielsen found the average time spent simultaneously using TV and Internet in the home grew 9.8%, to 3 hours and 41 minutes per month.
