This document provides an overview of the history and development of the Indian telecom industry from the past to the present and future. In the past, telecom services were run as a government monopoly from the 1800s until the 1990s. The 1994 National Telecom Policy began liberalizing the industry by allowing private operators. Currently, India has over 900 million subscribers and is one of the largest telecom markets. The industry has transitioned from a monopoly to an increasingly competitive private sector-led market. Looking ahead, further technological advances and investments are expected to help the Indian telecom industry grow substantially in subscribers and services.
