12% of American households own an Apple computer, up from 9% in 2008

"According to leading market research company The NPD Group’s 2009 Household Penetration Study, approximately 12 percent of all U.S. computer owning households own an Apple computer, up from 9 percent in 2008. While Apple ownership is growing, those households are decidedly in favor of mixed system environments. Of those 12 percent, nearly 85 percent also own a Windows-based PC.
Multiple computer ownership is a common thread in Apple computer households, with 66 percent of households owning three or more computers, compared to just 29 percent of Windows PC households.
Apple owning households are decidedly more mobile as well, with 72 percent of them owning a notebook, whereas only 50 percent of households that have a Windows PC own a notebook.
Not only do Apple computer owners own more computers (and more mobile computers) than the norm they also tend to own more types of electronics, and more of them, than typical computer owning households. For example, while 36 percent of total computer owning households have an iPod, 63 percent of Apple households have one. And while almost 50 percent of Apple owners own some type of navigation system, only about 30 percent of all computer households own one."

17% of the time Americans spend online is on social networking and blogging sites

"The Nielsen Company today reported that time spent on social network and blogging sites accounted for 17 percent of all time spent on the Internet in August 2009, nearly triple the percentage of time spent on the sector a year ago."
Note - this excludes video sharing sites like YouTube, which are effectively social sites, so the total percentage of time spent on social media sites would be much higher

Half as many US internet users click on ads as did 2 years ago

"The collaborative studies focus on an understanding of how U.S. Internet users click on display ads. The updated results based on March 2009 comScore data, and presented by comScore chairman Gian Fulgoni and Kim McCarthy, manager, Research & Analytics at Starcom, at the iMedia Brand Summit in San Diego on September 14, 2009, indicated that the number of people who click on display ads in a month has fallen from 32 percent of Internet users in July 2007 to only 16 percent in March 2009, with an even smaller core of people (representing 8 percent of the Internet user base) accounting for the vast majority (85 percent) of all clicks.
[...]
The original research, conducted using July 2007 comScore data, showed that 32 percent of Internet users clicked on at least one display ad during the month. These clickers were segmented into Heavy, Moderate and Light Clicking segments based on the group of users accounting for the top 50 percent of clicks (heavy), middle 30 percent (moderate), and bottom 20 percent (light). In 2007, comScore, Starcom and Tacoda found that heavy clickers represented 6 percent of U.S. Internet users, moderate clickers accounted for 10 percent and light clickers accounted for 16 percent. By March 2009, those numbers had dropped substantially in each case, to 4 percent of Internet users for heavy clickers, 4 percent for moderate clickers and 8 percent for light clickers."
