Affluent Americans spend more time on the Internet searching instead of surfing according to a JupiterResearch study. Americans with annual household income over $100,000 spend a median of 17 hours a week online, vs. 14 for everyone else. They also are more aware of advertising and are more active online. 20% of affluent people visit Web sites dedicated to business compared with 11% of others, and 37% of affluents do research for work online vs. 27% of non-affluents. 26% read blogs and 11% are blog-authors. Among non-affluents, those figures are 22% and 6%, respectively. (Marketing Daily 3/8/07)
