1. India is called the world office because it undertakes nearly half of the global service outsourcing market every year.

2. India is the most developed country in the software industry. As the country with the most BPO business in the world, India is considered to have the best elements to develop "service outsourcing" because of its low labor cost, high English level and strong calculator operation ability. The wage level in India is only 1/3 to 1/8 that of similar technicians in the United States, while the cost of rent, taxes and hardware in India is only about half that in Europe and America.
