The Schumpeter column in the current edition of The Economist is on how the revolution of big data and analytics is changing the landscape of business:
Companies are assembling more detailed pictures of their customers than ever before. Tesco, a British retailer, collects 1.5 billion nuggets of data every month and uses them to adjust prices and promotions. Williams-Sonoma, an American retailer, uses its knowledge of its 60m customers (which includes such details as their income and the value of their houses) to produce different iterations of its catalogue. Amazon, an online retailer, has claimed that 30% of its sales are generated by its recommendation engine (“you may also like”).
