Take a stroll to your local print shop and enquire how much it will cost to produce 1000 copies of an A4 sized, ten page document, in black and white.
Then start multiplying those figures up into tens of thousands or even more, add in distribution, warehousing &c.
Now you see why the WWW is such an attractive option for publishing, basically sero overheads (relatively speaking).
