The LAT’s story says this, paraphrasing a media analyst:
But it is likely to be a difficult transition taking many years. Atorino said the New York Times has not sold digital subscriptions at the rate he expected. He said most of the subscriptions it sells are highly discounted, diminishing the revenue gain. The company does not break out its revenue for digital subscriptions. Publishers believe that readers will pay for good journalism.
I’m not sure where Atorino got that information. I haven’t seen that anywhere.
