Ever heard of James Stewart? Well his name is on 80% of all Calculus books sold in North America. And when that happens, the money comes pouring in.
Eighty percent market share?! I thought the US was the land of free-enterprise, capitalism, competition. What about all those free, open-source calculus books: they can save the schools a lot of money! I think that somewhere high up in the tree someone is pushing one particular book through everyone's throat.
