The popularity of Amazon is indisputable. From a humble bookselling start-up in 1994 to eCommerce business giant, Amazon has come a long way. Amazon is holding its share of business in the cut-throat eCommerce business. No other competitor in many countries is anywhere near it. Amazon itself has an inventory of about 12 million items across all its categories and services but on a broader level all the items that Marketplace sellers list, that number expands to about 350 million. Amazon was responsible for 45% of US eCommerce spending in 2019 and is expected to rise to 47% in 2020.
