The Satellite Instructional Television Experiment (SITE) was a pioneering satellite communications project launched in India in 1975, collaboratively developed by NASA and the Indian Space Research Organisation (ISRO). This initiative is recognized as one of the most significant socio-technological experiments globally. Although Television was introduced on an experimental basis in and around Delhi in 1959, its expansion was slow and largely confined to metropolitan areas until SITE facilitated access to television for remote and underdeveloped regions of the country.

The technology for SITE was centered around the ATS-6, a powerful direct broadcasting satellite developed in the United States, equipped with a large nine-meter antenna that deployed in space similar to an umbrella. The primary objectives of the experiment included educating economically disadvantaged and academically illiterate communities in India on various relevant topics through satellite broadcasting, as well as providing technical expertise in satellite communications within the country.

The experiment was conducted over the course of one year, from 1 August 1975 to 31 July 1976. The project received endorsement from several international organizations, including UNDP, UNESCO, UNICEF, and ITU. The visionary Vikram Sarabhai, considered the father of India’s Space program, conceived the idea of SITE, emphasizing the potential of satellites to connect knowledge with India’s most remote regions rather than viewing them as instruments of conflict. During the initial phases of the project, the ISRO campus in Ahmedabad played host to a diverse group of professionals, including engineers, scientists, social scientists, filmmakers, folklorists, and playwrights, reflecting a commitment to interdisciplinary Collaboration.

In 1975, when television remained rare in urban areas of India, community viewing setups were established in schools and panchayat centers across 2,400 villages in six states: Bihar, Odisha, Madhya Pradesh, Andhra Pradesh, Karnataka, and Rajasthan. These villages, situated in some of the most economically and geographically challenged areas, often lacked electricity, prompting the use of automobile batteries to power the television sets. This arrangement allowed villagers to view programs focused on Health, agriculture, and development in four Languages: Hindi, Kannada, Odiya, and Telugu. Additionally, SITE provided educational programs designed for children and organized specialized Training for approximately 50,000 school TEACHers.

SITE exemplified ISRO's commitment to leveraging technology for solving pressing national challenges. It was initiated as an experimental project aimed at generating insights for a prospective operational system, ultimately leading to valuable learnings instrumental in the development of the Indian National Satellite System (INSAT). A comprehensive impact assessment study was conducted over the year, involving experts from various social science disciplines—including anthropology, Psychology, #sociology, and political science—as well as communication specialists, all of whom contributed to the analysis and evaluation of the project.

On 01 August 1975, India Post honored SITE with the release of a special 25 Paise stamp that features imagery of a satellite dish and television antennas, alongside symbols representing family planning, agriculture, Health, and Education.
