> It must be hard to sell adverts to Indian companies today ...

Not aware of the state of affairs presently but until a couple of years ago, I used to run AdSense on a handful of India-centric sites and while there were a good number of advertisers, I almost never got anything more than a crappy 1 or 2 cents per click out of it. (By contrast, on several other sites with a global audience, I used to easily average 12 to 15 cents per click.)
