A method for selecting and pricing advertising to accompany published digital content and printed copies of such content that people pass along to others via e-mail, print, blogs, RSS feeds, websites, hardcopy, and other distribution and republishing mediums. Ads placed in the passed-along content will typically be different from, and more relevant than, ads that were displayed with the content when it was presented to the first reader-who then decided to pass it along, and therefore the ads may be billed out by the publisher at a higher price because they now have greater value.
