If the Islamic State (also known as ISIS) is to continue to fund its brutal excess, it might focus less on extortion and more on the export of its high-leverage marketing strategies. JWT could learn a thing or two about how to grow a micro-business into a corporate land army from a group whose use of social and now traditional media has become nonpareil. The Islamic State’s latest low-cost beheading campaign has gone, as they say, viral. A perfect 10 out of 10 for effective use of a truly guerrilla media technique. Rather less, perhaps, for taking a Game of Thrones episode to its real-life extreme.
