Amazon was one of the three leading companies in the e-world (together with Google and Facebook) and the world’s largest e-commerce business, with annual sales of more than 100 billion USD. This case describes Amazon’s business model and e-commerce environment. It is interesting to analyze Amazon’s growth-based model and discuss its future. It is also worth exploring its current and future impact on retailing and the position of its offline competitors, especially after Amazon acquired the North American supermarket chain Whole Foods and entered the offline world.
