Types of paywalls implemented in the U.S. 2016

The source provides the follwoing explanation regarding subscription types: "Publishers are converging around models commonly referred to as “metered” — in which a number of articles can be read before subscription is required — and to a lesser degree “freemium” — in which most content is free, but “premium” articles or sections require a subscription. The so-called “hard” paywalls, where subscriptions are required to access the vast majority of the website, are extremely rare and declining."
The source provides the following information about the methodology: "To identify newspapers with circulations over 50,000, this report used the Alliance for Audited Media’s (AAM) Monday – Friday total average circulation figures for the six months ended September 2014. These figures include print, digital, and branded editions. Based on AAM’s disclaimer that seven newspapers no longer report 5-day averages but typically had circulations in the top 25 in previous reports, those seven newspapers were also included in the analysis."
