There are many reasons, mostly to do with skewed priorities. I'll describe one of ways priorities get skewed. There is a disproportionately large film and TV industry with a lot of political backing which are interested in getting TV into as many homes as possible. In the south Indian state I come from, one of the election promises by the current chief minister (somewhat equivalent to a governor in US) was a free TV for every family. The same minister owns a private TV Network. What best way to get more audience than use government money...
I bet you have a computer though. I also didn't have a TV for about 6 months, I never bothered to buy a new one after my last one broke. But I would guess that anyone that doesn't have a computer already is VERY likely to own a TV.
