The umbrella newspaper
Extra, the most popular newspaper in Ecuador, always experiences a sales drop during the rainy season. To avoid the problem of soggy newspapers they ran an experiment by laminating the front and back pages of the newspaper during those months. Not only did the pages remain intact and readable during the rainstorms, but the newspaper could also be used as an umbrella. Apparently this lead to a 12% increase in circulation and 16% more ad sales. More information can be found in this drupa blog article.
