Tatasky exchanging box with 1month free connection

Are you sure about this?Bro confirmed from Tata sky money of bigtv will be credited in Tata sky
They have 1-2 million subscribers active. So if Tata sky acquires all then it will be a good addition in their base.That means if TS manages to get majority of RDTV users on board, then their market share will increase by almost 1% which will overtake dishtv market share
