5 One Leaked File Nearly Brings Down AOL

Over the course of three months in 2006, AOL compiled search data on over 650,000 of its users. That might sound ominous, but all they wanted was a tool for researchers.

As a bizarre postscript to all of this, one of the users identified in the file only by number ("User 927") became internet famous for having basically the creepiest search habits imaginable.

Well, recently, a stage production premiered, based on their life, called User 927.
