In my personal opinion, VM make very little from the TV service as they always lost money from it and is mainly used as a retention tool. That is why you used to have to have a phone to get the TV service and currently you can only get the free package (size m) if you have a phone line.
Phone and BB make money, TV doesn't, so the only investment into TV is to keep customers on the BB and phone! (minimum to stop churn)
This isn't my perfessional opinion! (If you want that, PM me)
hic!
