Sony now occupies the #4 and #10 spot in the greatest data blunders ever

This graphic from Nathan Yau at Flowing Data shows the largest recorded data losses of all time.

Heartland Payment Systems still occupies the top spot after 130m records were lost in January 2009.

But, as you can see, after a spate of recent data blunders, including the loss of 77m accounts from the Playstation network, Sony now holds fourth and tenth place in the list.
