AC/DC tells the little-known story of how Thomas Edison bet wrong in the fierce war between supporters of alternating current and direct current. The savagery of this electrical battle can hardly be imagined today. The showdown between AC and DC began as a rather straightforward conflict between technical standards, a battle of competing methods to deliver essentially the same product, electricity. But the skirmish soon metastasized into something bigger and darker. AC/DC serves as an objective lesson in bad business strategy and poor decision making.
