Here's a snip of a recent PEW study:
http://www.pewinternet.org/PPF/r/252/report_display.aspA record-breaking 46% of Americans have used the internet, email or cell phone text messaging to get news about the campaign, share their views and mobilize others. And Barack Obama's backers have an edge in the online political environment.
Furthermore, three online activities have become especially prominent as the presidential primary campaigns have progressed: First, 35% of Americans say they have watched online political videos--a figure that nearly triples the reading the Pew Internet Project got in the 2004 race.
Second, 10% say they have used social networking sites such as Facebook or MySpace to gather information or become involved. This is particularly popular with younger voters: Two-thirds of internet users under the age of 30 have a social networking profile, and half of these use social networking sites to get or share information about politics or the campaigns...
The MSM is losing its influence. The right is way behind the left when it comes to online discussion, information sharing, community organization and political discussion.
The revolution is not being televised.
