Worst I've had was a chemistry 101 prof. With the knowledge, I'm sure, that chem 101 and bio 101 are far and away the most popular classes that fulfill science gen ed reqs, the professor chose not to write his own textbook but to create a (horrible) DVD with all the class content on it. Functionally, we're basically talking about chapters of powerpoint presentations with recordings by one of his T.A.'s explaining each diagram. This was a while ago, so I can't say how many sections of his 101 class there were (though he also taught 102), but we're talking in the neighborhood of 300-600 total students. $45 per DVD. Which you had to buy, because everything other than the exams (i.e. homework, quizzes) could only be submitted online...with a unique key from the DVD you bought. So assuming no royalties (he made the DVD himself), $45 * we'll say 400 students = $18,000 per semester. Minus the overhead of blank DVD's, to be fair.
