Every day, 2.5 quintillion bytes of data is generated by digital devices. This volume is expected to increase with the growth of Internet of Things (IoT). The data has been used by e-commerce websites for marketing, sales prediction and forecasting as well as targeted marketing, and companies take advantage of the digital foot prints that users leave on the internet while browsing. The data includes their location, brands of interest, gender, age, occupation, etc. It comes as no surprise, therefore, that when I perform an Amazon search for a book, I will see advertisements suggesting the same and related books once I log on to my Facebook account. This level of interconnectivity is used by platforms such as Amazon, eBay, and lots more to enhance their marketing efforts via artificial intelligence.
