(Los Angeles Times) 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.
