A Numbers Game.

From The Times last week:

"Of course, it is also possible to get overexcited about the internet. Penguin, the publisher, has a revenue-sharing agreement with Google, which allows it to profit from any advertising generated by its books on the search engine’s book service. This, of course, is dynamic, exciting stuff — a new revenue stream for book publishers and so on. Or maybe not. Last year Penguin’s share of the revenue amounted to $75. This year it may be $100, which, of course, would represent growth of 33.3 per cent."
