The Indian telecom industry has experienced rapid growth over the past two decades. Tele-density in India increased from 4% in 2004 to over 56% in 2010. The number of telephone subscriptions grew from a few million fixed lines in 1997 to over 671 million total subscriptions by June 2010, with wireless subscriptions reaching 635 million. Several government policies helped facilitate this growth, such as allowing private players to enter in 1992, establishing an independent regulator in 1997, and increasing foreign investment limits over time. The telecom sector is now one of the fastest growing and vibrant industries in India.
