Smith: http://scholar.google.com/citations?user=rzPlMfQAAAAJ&hl=en&oi=ao http://scholar.google.com/citations?user=rzPlMfQAAAAJ&hl... From the paper: Our [Megaupload] Internet penetration data is based ... Google AdWords estimates of the total number of unique visitors ... [and] ... the total number of Internet users in each country in our sample... As such, the shutdown of Megaupload influenced the policies of several other cyberlockers focused on piracy, and our results necessarily measure the “net impact” of the Megaupload shutdown across the cyberlocker industry, as opposed to just measuring the impact of Megaupload.
