[Poohbah]

If Harry Potter was just about teaching children to read, then why is Scholastic selling cassette tapes of the books for children to listen to, much less making movies about it?

Because they can make LOTS and LOTS and LOTS of MONEY?

Or is that motive a wee bit TOO obvious?

[jedediah smith]

Nothing wrong with making money, but the point is that Scholastic has virtually a nationwide monopoly on advertising their products to a captive, impressionable audience.
