1. “Hit Makers: The Science of Popularity in an Age of Distraction”
Derek Thompson
The Atlantic Senior Editor Derek Thompson explores what makes a hit a hit from an economic angle in “Hit Makers: The Science of Popularity in an Age of Distraction,” released this month.

“Hit Makers” is 352 pages.

With an optimist’s point-of-view, Friedman examines recent dramatic changes in technology, the global market and Mother Nature, and how people can utilize positive aspects of these changes to not only work for them, but to protect the future for all.
Released in November, this book is 496 pages.
