Paywalls were an attempt to preserve the old mass+mass model after a transition to digital distribution. With so few readers willing to pay, and therefore so few readers to advertise to, paywalls instead turned newspapers into a niche+niche business. What the article threshold creates is an odd hybrid — a mass market for advertising, but a niche market for users. As David Cohn has pointed out, this is the commercial equivalent of the National Public Radio model, where sponsors reach all listeners, but direct suport only comes from donors. (Lest NPR seem like small ball, it’s worth noting that the Times ‘ has convinced something like one out of every hundred of its online readers to pay, while NPR affiliates’ success rate is something like one in twelve. Newspapers with thresholds now aspire to NPR’s persuasiveness.) Paywalls encourage a paper to focus on the value of their content. Thresholds encourage them to focus on the value of their users.
