I can give some concrete evidence to bishnu sir
as per the following post by telecom talk showing official documentation by tai
Source
as of march 2014 there were total 65 million subscriber of dth out of which 37 million are currently active and you say that sun has 10 million active subscribers. Which means tata sky,airtel,videocon,dish,rdtv, has about 27 million active subscibers?
I dont think that number is correct.
Also dont tell me that in 9 months dth must have added a lot of subscribers at this point of time the number must have changed by 2-3 million at the max.
A plausible way to calculate sundirects active subsciber base would be to see that about 50% of dth connects are active in total(as per trai) so it is safe to assume that sundirect has about 50% active subscriber base (give or take) which is about 5 million which is a good number and fits the statistics given by trai.
Sorry if it was long.
