I strongly suspect that the data comes from Microsoft's MSN page. Video downloads is really the only usage scenario broad enough to generate such a data set. MSN serves loads of them and is the default page on Windows. Since their contents target the audience favored by advertisers (i.e. young urban folks with money), the data could have a strong selection bias. Rural Americans simply aren't viewing the pop-culture-centric materials on MSN.
