There are--and it is kind of technical--different ways to purchase Internet. They have different cost structures, and they do different things. You can buy in a particular website, and that's easy, right? You buy in a website, and you know where you're placing your ad. The way the payment structure works on these things is that you pay by performance. They call it “cost per thousand”. It takes 1,000 people to click through for that service provider to get a certain amount of money. In those instances, because it takes a lot of click-throughs, they charge a little bit more.
There's another type of ad placement called run-of-network. When somebody clicks on to an Internet site that seems to have the same type of target audience that you're going after, the ad is served to them. That is typically a less expensive buy, but with it is a little bit of a higher risk, because you're not predetermining where they will all land. You're dependent on the use of these filters to say you don't want your ad to be served to any of these sites. We work very hard on those filters. The thing is, as you can appreciate, the Internet evolves, and new sites are added every day. Sometimes it's even hard for Cossette to work with the representatives from these sites, and the representatives don't even know necessarily how many new ones have been added.
Someone asked before about the types of things we do to sort of keep constant and to introduce new checks and balances into the system, and that would be one of them. We try to build in increased safeguards as new technologies and challenges are thrown our way.
