Steve, the Beeb has no preferences in my opinion. I believe they have the same view that Jon just expressed (with which I agree, by the way). They ask the agents, and the agents suggest.

Now, let's not bemoan Eliza's, or Kate's or Seth's use of publicity agents or managers. When that is your livelihood, you go about it as professionally as you can, and using the tools the market provides. They are doing nothing wrong, and good luck to them.
