Amazon is definitely one of the world’s premier commercial recommender systems, with its precise recommendations still generating immense benefits for the website itself even today. Approximately 30%–40% of Amazon’s revenue is derived from product recommendations. Physical stores can provide only bestselling or newly launched products because of regional constraints, limited inventory space and cost. According to the 80/20 Rule, 80% of a vendor’s revenues are generated from only 20% of products. Most products cannot appear on the shelves in physical stores, or are ignored by customers. In the past decade, the rise of e-commerce has reduced the cost of displaying products for sale. The recommender system has engendered business opportunities for products that were previously unknown to consumers. Products that previously had failed to attract consumers’ attention could be recommended to them through this system, greatly increasing the probability that they would be purchased. According to statistics, 57% of Amazon’s sales and 20% of Netflix’s sales were derived from products that are not sold in physical retail stores.
