Paywall
A paywall is a method of restricting access to content via a paid subscription. Beginning in the mid-2010s, newspapers started implementing paywalls on their websites as a way to increase revenue after years of decline in paid print readership and advertising revenue. In academics, research papers are often subject to a paywall and are available via academic libraries that subscribe.
Delfi (web portal)
In February 2016, most of the English language version's contents were placed under a paywall to restrict access to most articles without a paid subscription, as the articles in this version of Delfi are supported by the Lithuania Tribune, which raised questions on implementing the paywall there. It is unknown if other language editions will be implementing the paywall.
