Tata Sky is not so important as they themselves think about them . Movies Now became No.1 in India even when they were not on tata sky.
Also almost half of dth connections r inactive ans major chunk of them would be from tata sky, dish tv, reliance, sun direct. Airtel and Videocon still command a great % of active subscribers.
Majority of viewership still comes from cable tv especially from analogue cable so broadcasters r not that worried about these fights.
Also until there r dth ops with vested interest in their respective sister networks till then there will be fights with competition networks.
