CNN.com, the most-visited news website in the United States, will introduce a paywall in early October. The model will require frequent visitors to pay after reading a certain number of articles, following the strategy employed by other publishers such as The New York Times. CNN will keep a close eye on how users respond to the initial low-cost subscription offering, and is ready to adjust as necessary. Amid declining viewership for cable news, the network has been struggling to adapt, particularly after its CNN+ streaming service failed to take off and was ultimately being shuttered due to high costs.
