"Three Amazon inventors set out to correct what they felt was a real problem: that 'out-of-print or rare books ... typically do not include advertisements ... the content is fixed and, therefore, has not been adapted to modern marketing.' Their solution is spelled out in newly-disclosed Amazon patent applications for On-Demand Generating E-Book Content with Advertising and Incorporating Advertising in On-Demand Generated Content."
That is just plain crazy! As if we aren't subjected to enough marketing already! Greed, greed, greed! Let's call it what it is: SIN.
