“The Center for the Digital Future at the USC Annenberg School is pleased to present the results of the sixth year of our project, “Surveying the Digital Future.” The six years of longitudinal research comprise an absolutely unique data base that completely captures broadband at home, the wireless Internet, on-line media, user-generated content and, now, social networking. This year’s report contains a large module looking at on-line communities and social networking in great detail. Readers can compare the social networking data and correlate it to six years of attitudes and behaviors on-line. As usual, the report continues to track off-line media use, purchasing both off-line and through e-commerce, social and political activity and a wealth of other data.”
