In a stunning move, BBC News reports that AOL is buying the Huffington Post. The Media Network blog at Radio Netherlands Worldwide notes that Arianna Huffington will move from being editor of a center-left group blog to heading up AOL's content division including properties like TechCrunch, Engadget, Moviefone, Mapquest, and more. The LA Times reported that this is AOL's largest acquisition since it was divorced from Time Warner. Advertising Age reports that the content properties will be merged into the "Huffington Post Media Group". The Tatler, the group blog of center-right media group Pajamas Media, also weighed in on the acquisition.
