Chennai Doordarshan devised its programmes without copying any other channel and made the viewers spellbound through its variety of informative, educative and entertaining programmes.
When popular programmes of Chennai Doordarshan were on Air like feature film or film songs, you could notice empty streets as people thronged to television sets at home, at neighbouring houses, television shops, etc.
In the initial stages, Terrestrial Transmission of Chennai Doordarshan could reach only a short distance from its origin. To make other parts of Tamil Nadu view Chennai Doordarshan's programmes technology was utilized. High Power Transmitters and Low Power Transmitters were installed at vantage locations and the transmission reach was expanded to the entire area of Tamil Nadu.
Then came the Satellite Technology. Doordarshan's Regional Language Satellite Channel Podhigai was started and the programmes were received not only in India but also by many foreign countries.
Growth of Satellite Technology resulted in the advent of many Private Channels. Though Chennai Doordarshan lost its dominance and monopoly, it can take pride from the fact that many of the programmes devised and telecast by the Private Channels were based on the programmes already telecast on Chennai Doordarshan.
In spite of stiff competition, DD Podhigai continues to command respect and confidence among the Tamil people all over the world because of DD Podhigai's socially relevant and dignified programmes, not employing the negative tactics used by some of the other Private Channels to increase their TRP in their struggle to earn money.
DD Podhigai continues to be a people's channel, as the programmes of DD Podhigai caters to all walks of the society be it a farmer, industrial worker, student or a general public.
