Classics, history, historical fiction, marketing, Napoleonic stuff and of course 'Boys own Adventure'. This is my bent. Occasional self help as well.
Valuable insight into why somethings take off and others possibly flop. Not sure if "The Tipping Point" is the answer or one of the contributors to why things happen. My experience is that everything is connected to each other in various degrees, but this book sure puts a good case for the authors theories. A little confusing in parts, but the authors voice is easy to listen to. A valuable book for marketing type people. Worth the listen to.
