According to a new study, 65 percent of American adult Internet users have interacted on a social media site like Facebook, Google+, or LinkedIn, supporting the often cited importance of social media marketing.

The social networking report from the Pew Internet & American Life Project has been asking adult Internet users in the United States about social media site visits since 2005 when just 8 percent of Internet users 18-years-old or older had visited one of the sites, compared with 65 percent just six years later. What’s more, for the first time, more than half of all American adults — Internet user or not — has visited a site like Facebook, LinkedIn, or Google+.
