Cho played a major role in introducing satire about socio-political issues, to the Tamil audience, through his magazine. The intelligentsia would often agree with his though-process that was usually well ahead of his times.
In fact, during the Emergency era, Tughlaq was the only magazine whose advertisements were censored. When the publication resumed after emergency, the first issue was boldly published with just a black front cover as a mark of protest.
Cho entered the film industry and made his debut in 1963 with Paar Magale Paar as a comedian. From 1963 to 2005, he has acted in 190 Tamil films. In the recent past Cho had directed the adaptation of his book ‘Enge Brahmanan’ (Where is the Brahmin?) into a television series.
