“As part of the class-action settlement” of a federal lawsuit over book scanning, “Google will pay $125 million to create a system under which customers will be charged for reading a copyrighted book, with the copyright holder and Google both taking percentages; copyright holders will also receive a flat fee for the initial scanning, and can opt out of the whole system if they wish. But first they must be found.” Thus Google’s $7 million advertising effort “in that relic of the pre-Internet age: print.”
