Sun TV Network owns two Radio brands: Suryan FM in Tamil Nadu and for other territories Red FM. Sun is one of the largest Radio broadcasters in India. It has become our second nature to occupy the first slot in whatever we do. Sun Group's foray into FM radio is no exception either. Tamil's first private FM stations - Suryan FM - from Chennai, Coimbatore and Tirunelveli is way ahead to its competitors. The top slot is a result of a carefully planned thoroughly enjoyable, round-the-clock, wholesome entertainment-oriented package and there is a substantial localization of content to retain the regional flavor.
