The document discusses the evolution of the New York Times' paywall system, beginning with early attempts at subscription fees in the 1990s and culminating in the 2011 launch of a metered paywall model allowing 20 free articles per month.

Ultimately, while digital subscriptions increased, they also contributed to a decline in print subscriptions, indicating a complex relationship between the two media forms rather than a straightforward substitution.
