Print ads are not targeted--they can only be targeted to the text they accompany. This means that the vast majority of their viewers are completely uninterested in the ad, while a viewer who might be interested in an ad that shows in another print item, does not see that ad because they do not subscribe to that print item. Digitization allows for ads to be switched on-the-fly, so no matter that media you consume, you see ads relevant to you. This vastly increases the success rate of the ads. It doesn't seem like much, because even targeted ads have an incredibly low success rate, but there's a huge difference between 0.0001% and 0.01%.
