Another study showing increased use of Online Video.

Respondents to Ericsson’s “TV & Video Consumer Trend Report 2011” largely confirmed what several other Cross-Media studies this summer found - that more viewers are watching more online video.  38% of their sample reported watching "internet-based on-demand" TV more than once a week.  Somewhat more surprising, only 80% of the sample reported watching broadcast TV more than once a week.  While the percentage is high, it's also lower than what has been considered typical. Viewing habits are also changing - 40% of the sample reported using social media while watching TV.
In a statement released with the study, an Ericsson rep was careful to not suggest a simple transition from viewing from broadcasts to online, from passive reception of delivered content to a more interactive selection of preferred content.

 “People want both broadcast and on-demand viewing to be available. TV and video have not been negatively affected by the internet in the same way that print has; we just watch TV in many more ways than we did before.”

The study is based on more than 13,000 interviews in 13 countries.
