Makes me wonder about those sketchy "start your own online business!!!11" TV ads I've been seeing recently, which have one of at least twenty different URLs at the bottom: www.[random 2-digit number][random three letters][one of a few words vaguely relating to the scam].com

Progressive insurance does this as well. I honestly think that this is simply a way for them to track which TV ads are getting responses and which are not, so they can more effectively target their marketing.

But I could be completely wrong. At least Progressive's ads pointed you to progressive.com/$foo
