In academic publishing, an embargo is a period during which access to academic journals is not allowed to users who have not paid for access (or have access through their institution). The purpose of this is to ensure publishers have revenue to support their activities, although the impact of embargoes on publishers is hotly debated, with some studies finding no impact while publisher experience suggests otherwise. A 2012 survey of libraries by the Association of Learned, Professional, and Society Publishers on the likelihood of journal cancellations in cases where most of the content was made freely accessible after six months suggests there would be a major negative impact on subscriptions, but this result has been debated.

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.Paywalls have also been used as a way of increasing the number of print subscribers; for example, some newspapers offer access to online content plus delivery of a Sunday print edition at a lower price than online access alone. Newspaper websites such as that of The Boston Globe and The New York Times use this tactic because it increases both their online revenue and their print circulation (which in turn provides more ad revenue).
