Social networks continued their domination of our lives in 2012 with U.S. users logging more than 121 billion minutes across numerous social networks in just July of this year.
Put another way, that's more than 2 billion hours of viewing vacation photos and reading about a friend's new puppy.
That's up 36% from 88.4 billion minutes spent on social media in July 2011, according to Nielsen's recently released 2012 social media report.
Facebook alone accounts for a major portion of that time. U.S. users spent more than 62 billion minutes on Facebook on their computers alone -- up 23% from last year. That accounted for 17% of the total time spent on our computers.
Throw in Facebook's mobile site and apps, and we actually spent 93.3 billion minutes on the Menlo Park, Calif.,-based social network.
But Facebook wasn't the only social network to post impressive numbers.
Twitter, Tumblr, Google+ and Pinterest each saw their computer and mobile app unique U.S. visitors grow whopping percentages. The most notable growth belonged to Pinterest, which exploded exponentially and increased its computer audience by more than 1,000% and its mobile app audience by nearly 1,700%.
Mobile social media activity also made large gains this past year.
According to the report, we now spend a third of our social media time on mobile apps, and the amount of time we now spend on social apps grew by 76% from last year.
Other notable highlights for the report, which you can see in detail here, include these tidbits:
