Example of Content Creation / Marketing from "The Economist" Magazine
I subscribe to "The Economist", which is weekly magazine. About a month or so ago, they started a free weekly newsletter for subscribers which describes how they decided on that week's cover. The newsletter takes you behind the scenes, and shows their thinking about what they are trying to illustrate, their evolving thought processes, and earlier iterations of the cover—until they end up with that week's final cover picture.
I think this is a clever idea for content creation
