I personally know a few people on their media team, the ones responsible for these relationships, and it sounds like they have 1-3 people per genre (tv, music, government), at least in the US. The amount of media they get on television alone is likely worth multiples of that if you think how expensive it is to buy tv spots, even if you try to normalize for the "Twitter shout outs." Maybe a lot of resources, but nothing compared to the engineering.
