Nielsen Social Media Report Says We Facebook and Pinterest a Little too Much

The United States spent 121 billion minutes on social media sites in July 2012 alone, according to Nielsen's annual Social Media study reported by NBC News.

The report, titled "Social Media Comes of Age," found that Facebook is by far Americans' preferred social network. One hundred-fifty two million users visit Mark Zuckerberg's legendary website from their personal computers, while 78.4 million check their statuses from the mobile app (and 74.3 million check their profiles via the mobile web).  

But the study, which surveyed 1,998 social media users ages 18 and older between July 19 and August 8, wasn't all about Facebook. Popular pinboard site Pinterest came out as one of the "breakout stars in social media for 2012" by getting the largest "year-over-year" increase in unique visitors and time spent on the site.

Other findings tell that U.S. users spend approximately 20% of their time on personal computers, and 30% on mobile gadgets such as smartphones and tablets. That's 50% of our time devoted to post and 'like' statuses as well as 'checking in' on locations and uploading or commenting on images, memes, and GIFs.
