http://www.brandweeknrx.com/2007/08/abbott-caught-a.htmlSeveral drug companies have now been caught deleting important information from Wikipedia, in order to downplay the risk of their drugs.
The first drug company caught messing with the Wikipedia was AstraZeneca. References to claims that Seroquel allegedly made teenagers “more likely to think about harming or killing themselves” were deleted by a user of a computer registered to the drug company, according to Times.
According to Patients not Patents, now it is Abbott Laboratories who've been caught doing the same thing. The group alleges that "employees of Abbott Laboratories have been altering entries to Wikipedia, the popular online encyclopedia, to eliminate information questioning the safety of its top-selling drugs."
The tool used to catch these corporate erasers is the WikiScanner, which was developed by Virgil Griffith, a researcher at the California Institute of Technology, and it reveals changes to the online encyclopaedia by linking edits back to the computers from which they were done, using each computer’s unique IP address. The scanner has wreaked havoc in news media, politics and among corporations caught redhanded "improving" articles.
