Digital media continue to (1) erode the demand for daily print content, (2) depreciate the value of print ad space, and (3) divert more advertising budgets to online media. What each of these trends indicates is that the conventional newspaper distribution and revenue models are obsolete — they both fail to address modern market realities. Newspapers, then, musta dapt to a predominately digital landscape by evolving into social news organization (SNOs).
Essentially, the newspaper business model focuses on (1) producing authoritative content so that they can (2) sell advertising. There is nothing in that model that necessitates that content be printed on actual paper or that readers pay for their subscriptions.
An SNO also uses up to four channels to grow and maintain its registered user-base and generate revenues: SEO, social media, the mobile web, and an optional (free) print edition.
