wakeup. by agriculture, it does not mean only working in the fields-- food processing,dairy,poultry are all part. also rajeev said IP generation. IP generation can be in any field: medicene, pharma, electronics. FYI: the 3 names that you have mentioned above are classic cases of NOT generating any IP, but using the IP generated by someone else profitably. As an example,I can take any bet that the next for the big thing in IT--''nano tech'' India's contribution will be miniscule.
