Idle thought:

Surely (niche) newspapers for cities, or big gatherings that want to accrete more people, would have modular content, and would easily tear down into handbills?  Content on one side, slogan/image/information on the other.  Each module having its own discrete web address (shortcode) printed under the article.  And a bit of the last page would tear down and then fold into notepaper.
