Why don't Rajni n Pawan Prefer ADS?

It has been quite a strange thing from South Indian top stars such as Rajnikanth, Kamal Haasan and Pawan Kalyan, who do not prefer  endorsing any brands from corporate sectors. When we tried to dig the facts behind this, it is known that the above stars are not interested  doing ads as they feel it would be monotonous if they act in ads, as nowadays, many actors, who include from stars to small hero, heroines are doing ads. Moreover, they are not very much interested in money earning through other sources rather than acting. However, Pawan Kalyan got the credit of first South Indian hero among his contemporaries, to have endorsed a corporate brand( Pepsi) long back. Later, he gave up doing ads and is only concentrating on acting. 

Currently, Rajnikanth is busy with his 'Kochadaiyan' movie's shoot. On the other hand, Kamal Haasan's 'Viswaroopam' is all set to release. Pawan Kalyan's 'Cameraman Gangatho Rambabu' is releasing on 11th October.
