For centuries, putting something on paper (disk, etc.) and distributing it has been exclusive to huge media companies. Anyone can create a website or a start a dry cleaner, but publishing has been traditionally dominated by gigantic media houses. No more.
Along comes Lulu and enables anybody to publish a book. A real book - with hearty paper, professional covers, and a listing in the Library Of Congress! One at a time, they turn them out. For less than the price of a DVD player you can even have your book distributed through the same mainstream channels from which companies such as Barnes & Noble and Amazon buy their inventory. The book certainly will not market itself, but it is definitely there in front of decision makers where it would never have been otherwise.
Lulu has turned an entire industry on its ear by giving power back to creators and customers, alike. For industries like pharmaceuticals, where huge companies took the power of independent pharmacies, the pendulum is swinging backward, too. Small grew too big and now hopes to be small again.
