During this time, Amazon Prime was introduced, a membership program offering a wide range of benefits, such as unlimited free fast delivery and access to Prime Video and Music. This initiative significantly enhanced the user experience and set Amazon apart from its e-commerce rivals. The launch of Amazon Prime was aligned with the company's strategy focused on customer satisfaction, providing convenience along with a variety of services for a reasonably priced annual fee. Additionally, their marketing strategy leveraged the idea of 'free shipping', which was relatively rare and costly for retailers at that time. This not only increased competitive advantage but also attracted both consumers and investors, making Amazon's stocks more appealing. Thus, I believe that the introduction of the Prime membership program, along with a well-planned marketing strategy to promote it, greatly contributed to the rise in Amazon’s share prices during this period.
