Amazon (AMZN) continues to rewrite the rules of the retail industry. The world's largest online retailer is consistently working on the next groundbreaking technology or method of doing business. It's no secret that Bezos will spare no expense in building up the company's distribution and delivery infrastructure. The company spent roughly $2 billion alone on those segments last quarter. AMZN's strategy is to speed up delivery, both to optimize inventory turnover and to give consumers as few reasons as possible to shop at brick and mortar stores. That being said, Amazon's latest innovation is something out of a sci-fi movie. The company plans on using drones to deliver packages, with delivery times often within 30 minutes. It's going to be 4 to 5 years before delivery drones become a reality. Nevertheless, it's an ambitious idea and again proves AMZN in on the cutting edge.
