One in five divorces are blamed on Facebook. And 69% of parents are friends with their children on social media. Those are just two of the facts included in the latest installment of “Social Media Revolution.”

The video is produced by Socialnomics author Erik Qualman, who has created several similar videos and has updated them as new data surfaces.

The latest video in the series is updated with data up to June 2011 and contains several interesting highlights:

• Lady Gaga, Justin Bieber and Britney Spears have more Twitter followers than the entire populations of Sweden, Israel, Greece, Chile, North Korea and Australia.
• Groupon will reach $1 billion in sales faster than any company in history.
• Social gamers will buy $6 billion in virtual goods by 2013.
