Amazon is one of the world’s biggest and, without any doubt, one of the world’s leading retailers. Also, Amazon remains ahead in the e-commerce market in the US and in the rest of the world. Amazon.com aired in the summer of 1995, and since then Amazon has managed to turn its business from being a digital bookstore into being an Internet-based product giant. Today, it is almost impossible to find any items that Amazon does not sell. Moreover, the company’s ability to think strategically, innovatively, and farsighted at the same time holds importance. These abilities are all rooted in CEO and founder of Amazon, Jeff Bezos’ way of thinking, but also shared by many of Amazon’s current employees. Being a giant has its consequences. As Amazon expands into more verticals, its sheer number of competitors has exploded, and they are attacking Amazon in ways that are both big and small. To keep hold on the market, Amazon will do whatever it takes, so whatever you understand is correct.
