Over the years, it introduced various services to cater to the diverse needs of the Indian audience. These services include External Services, Vividh Bharti, News Services, and Commercial Broadcasting. External Services began in 1943. Initially, this service aimed at broadcasting programs to foreign audiences, particularly during World War II. As a result, it played an essential role in promoting India’s interests globally and reaching out to the Indian diaspora. Next, Vividh Bharti, launched in 1957, became one of the most popular entertainment channels on AIR. This service offered a wide range of programs, including music, dramas, and news, and it became a household name. Therefore, Vividh Bharti contributed significantly to AIR's popularity. Furthermore, News Services, which started in 1936, laid the foundation for AIR’s role in delivering official announcements. Through this service, AIR could effectively reach people with updates and critical information. In addition, Commercial Broadcasting, which began in 1967, marked a significant shift. It enabled AIR to generate revenue through advertisements, thus contributing to its financial sustainability. In conclusion, each service, although introduced at different times, has contributed to shaping AIR's role in Indian society. While the External Services reached global audiences, Vividh Bharti became an entertainment hub, and News Services delivered essential updates. Additionally, Commercial Broadcasting introduced an important source of revenue, making AIR a more self-sustained media organization.
