Two-Thirds of Global Internet Users Access Social Networking Sites

Of the 1.1 billion people age 15 and older worldwide who accessed the Internet from a home or work location in May 2009, 734.2 million visited at least one social networking site during the month, representing a penetration of 65 percent of the worldwide Internet audience.

Brazil ranked close behind at 6.3 hours, followed by Canada (5.6 hours), Puerto Rico (5.3 hours) and Spain (5.3 hours).

Social networking has become a popular online pastime not only in mature Internet markets like North America, but also in developing, high-growth Internet markets such as Russia, said Mike Read, SVP managing director, comScore Europe. In a country as geographically large as Russia, social networking represents a way of connecting people from one corner of the country to the other. The highly engaged behavior of social networkers in Russia offers significant opportunity for marketers and advertisers seeking to reach these audiences.
