Brandweek reports on a report from Sharpe Partners that shows that 89% of US adult Internet users send content others. 63% do so at least once per week, and an amazing 25% share content nearly daily. As many as 3/4 of the respondents to the survey forward content to up to six others. The study also found that overt branding only has a slightly negative effect on a viral campaign. Intuitively, I would have suspected that overt branding would have hurt more than that.
