Los Angeles — A recent Nielsen research report finds that Americans tend to watch less TV when they engage in more online video viewing.

Overall TV watching was up 0.2% (22 minutes) per month per person over 2010, while mobile video viewing was up 41% over last year, and more than 100% since 2009.

Of the nearly 2,600 online video viewers polled by Nielsen, the percentage that watched the most online video also consumed the least amount of TV, averaging 4 hours, 32 minutes per day, while those who watched little or no online video were the heaviest TV viewers, averaging 4 hours, 50 minutes per day.

The survey was broken down into different categories, including by ethnicity — and showed that African-Americans watched more tradition television and video on mobile devices than any other ethnic group.
