The New York Times has said it will start charging North American users for some of its online content. The newspaper will initially charge readers in Canada, with its US audience facing charges from 28 March.
Different charges will apply depending on whether readers use a smartphone, a computer or an iPad. The newspaper hopes to make up for lost revenue as newspaper sales have fallen and as advertising earnings have slipped.
"Our decision to begin charging for digital access will result in another source of revenue, strengthening our ability to continue to invest in the journalism and digital innovation," said chairman and publisher Arthur Sulzberger Jr.
The newspaper is eager not to alienate its existing readers online, so each month the first 20 articles will be free. Readers will then be charged:
* $15 (£9) per month for unlimited access to the website and its smartphone app
* $20 per month for unlimited access to the website and an iPad app
* $35 per month for unlimited access to the website, a smartphone app and an iPad app.
