I think the distinction between what is used for commercial purposes and what I already described is in the example of pharmaceutical companies that spend enormous amounts of money on research and development to come up with new therapeutics, and so on. They need to develop their strategies. They need to understand disease states and what's coming in the future.
We have an aging population that's very concerned about what kinds of medications they're going to need to be developed. The pharmaceutical companies need to enlist physicians for clinical trial purposes, they need to provide information for continuing medical education purposes to the physician community, and they also need to provide general information about their products specifically to the medical communities and to the pharmacy sector as well.
So I think that's the clear distinction you can make between the antibiotic usage I gave you, where you have real clinical research, and then the more commercial needs.
