More pages to display more ads unfortunately. The sheer amount of scripts running all over the chron website make its performance absolutely terrible, even before you consider how intrusive the ads themselves are.
When you use an adblocker the amount of ads it shows as blocked is unbelievable. They'll be hoist by their own petard in the end; I fully appreciate ads are their main form of funding these days and don't mind seeing a few, but the sheer volume they throw at you affects load times to such a degree the site becomes unusable. In fact, the Chron website was the only reason I installed an adblocker! And yes, in the end if everyone uses an adblocker we'll lose the site altogether, so it's a catch 22 situation...
