But then, manna descended. The tech team had finally built a way for us to publish a slideshow. Until then, The Big Money didn’t have the capability to run simple photo galleries that would earn a page view—and display a new ad—after every new click.

Over the next few days, the slideshow made up 40 percent of our total traffic.
