Airtel possible took an intelligent gamble, they decided to go for Sun HD over the 2 malayalam channels for 2 reasons. One they were probably losing more customers in TN than KL and because its world cup season and KL people won't bother with anything else. Besides people take new connections during Onam and they probably decided to concentrate for KL during that period. Anyway DTH services are no match for local cable in almost all southern cities. Only those who bought by mistake are still using it.
