Will Amazon's Same-Day Delivery Model Hurt Newspapers?

In Nieman Journalism Lab blog post, Ken Doctor explores the possible effects of Amazon’s shift into same-day delivery on newspaper advertising revenues:

Here’s what most hurts most about the new Amazon threat: It aims directly at the one category of newspaper advertising that has fared the best, retail.

Classifieds has decimated by interactive databases. National has migrated strongly digital. Retail, which made up of just 47 percent of newspaper ad revenues 10 years ago, is now up to 57 percent of newspaper totals. Now that advertising, albeit in just a few markets initially, will have to compete with Amazon-forced marketplace change.

Doctor also considers the implications of the move for Google, cityscapes and shopping centers, and employment.
