Most of the major browsers have offered some form of stealth for a couple of years. I think some of them call it “incognito”. I think each browser has its own nomenclature for it. Those have been in existence for a number of years. To the extent that it provides users with some comfort that those Internet browsing sessions will be subject to the incognito rules, I think that's a good thing. We haven't seen stealth or incognito having a significant impact upon the BlueKai business to date.
