The Pew Research Center's Internet & American Life Project has released The State of Online Video.
Here's an excerpt:
On the other side of the camera, video creation has now become a notable feature of online life. One in seven adult internet users (14%) have uploaded a video to the internet, almost double the 8% who were uploading video in 2007. Home video is far and away the most popular content posted online, shared by 62% of video uploaders. And uploaders are just as likely to share video on social networking sites like Facebook (52% do this) as they are on more specialized video-sharing sites like YouTube (49% do this).
Yet, while video-sharing is growing in popularity, adult internet users have mixed feelings about how broadly they want to share their own creations. While 31% of uploaders say they “always” place restrictions on who can access their videos, 50% say they “never” restrict access. The remaining 19% fall somewhere in the middle. And while there is almost universal appreciation for the ease with which video-sharing sites allow uploaders to share video with family and friends, a considerable number (35%) also feel they should be more careful about what they post.
