 And what Tedellis and his colleagues did as an experiment was they said, you know, a lot of people who click on the ad, they were searching for eBay. They were intending to buy something on eBay. They just wanted to find the web address so they could click on it. And if we don't advertise, we'll get just as much revenue because instead of clicking on the ad, they'll click on the organic search result, which will come up first. So that was a case where there was a claim, but no evidence that the ads were leading to the purchases. And that could well be the case with the spokesperson.
