Both these companies are in trouble because both of them have done different deals with the same Indian retail company Future Group. Experts say that the future of e-commerce in India depends on this legal battle of Reliance with Amazon in the coming years.
Satish Meena, a senior future analyst at Forrester Consultancy, told the BBC, "I think it's a big deal. Amazon has not faced such a rival in any market."
Amazon has made its founding owner Jeff Bezos the richest man in the world. (Although he is no longer the richest man, Mukesh Ambani has left him behind) Amazon has changed the business of retail on a global scale. But Mukesh Ambani, the owner of Reliance, is also India's richest man and his history has not given up so easily.
