All –

This was a screw up, and we’re angry and upset about it. It was an innocent enough attempt to reach out to the academic community with new research tools, but it was obviously not appropriately vetted, and if it had been, it would have been stopped in an instant.

Although there was no personally-identifiable data linked to these accounts, we’re absolutely not defending this. It was a mistake, and we apologize. We’ve launched an internal investigation into what happened, and we are taking steps to ensure that this type of thing never happens again.

Here was what was mistakenly released:

* Search data for roughly 658,000 anonymized users over a three month period from March to May.

* There was no personally identifiable data provided by AOL with those records, but search queries themselves can sometimes include such information.

* According to comScore Media Metrix, the AOL search network had 42.7 million unique visitors in May, so the total data set covered roughly 1.5% of May search users.

* Roughly 20 million search records over that period, so the data included roughly 1/3 of one percent of the total searches conducted through the AOL network over that period.

* The searches included as part of this data only included U.S. searches conducted within the AOL client software.

Our apologies again.
