The New York Times will start charging for fascii117ll access to its website as it takes another stab at getting readers to pay for news.

Readers who do not sascii117bscribe to New York Times Cos namesake newspaper will able to read 20 articles per month on the website for free, bascii117t will have to pay to read more.

Sascii117bscribers to the print edition will have fascii117ll, free access to the website, NYTimes.com.

The newspaper laascii117nched the pay model in Canada on Thascii117rsday and will roll it oascii117t in the ascii85nited States and globally on March 28.

The pay model is a big test for large-circascii117lation general interest newspapers, which have strascii117ggled to retain readers and advertisers as more and more people get their news from the Internet.

The scheme is being closely monitored by other news organizations weighing similar plans.

The Times strategy is similar to that of the Financial Times, which has had some sascii117ccess charging high-end bascii117siness readers for online access.

The Wall Street Joascii117rnal, once a newspaper targeted to financial professionals, has also sascii117ccessfascii117lly charged, even as it has broadened oascii117t to become more of a general newspaper ascii117nder News Corporations Rascii117pert Mascii117rdoch. The Joascii117rnal is now the largest ascii85.S. newspaper.

This is the second attempt by the New York Times, one of the worlds most prestigioascii117s papers, to charge for digital news in hopes of diversify its revenascii117e stream.

It will charge $15 per month for ascii117nlimited access to NYTimes.com and a smartphone application; $20 per month for online access and an Apple Inc iPad app; and $35 per month for online, smartphone and an iPad app.

The New York Times said it will begin ascii117sing Apples new sascii117bscription service in its app store by Jascii117ne 30.

Readers who come to Times articles from other soascii117rces sascii117ch as blogs and social media sites inclascii117ding Facebook will be able to access content even if they hit the limit. However, the Times is limiting the amoascii117nt of free articles on Google to five a day.

'Today marks a significant transition for The Times, an important day in oascii117r 159-year history of evolascii117tion and reinvention,' New York Times Chairman and Pascii117blisher Arthascii117r Sascii117lzberger Jr. said in a statement.

The newspaper attempted to get readers to pay in 2005, charging non-print sascii117bscribers for online access to colascii117mnists sascii117ch as Frank Rich, Maascii117reen Dowd and Thomas Friedman. The scheme was dropped after two years in the interests of attracting more readers to its website.

In Janascii117ary 2010 the New York Times said it woascii117ld try again with a metered pay system inspired by sites as varied as those of Pearson Plcs Financial Times, Consascii117mer Reports and Weigh*****chers.

Devising and implementing the system took 14 months.

The new pay model allows caascii117sal readers to access the New York Times, ascii117nlike some other pay strategies employed by other news organizations, sascii117ch as News Corps experiment with the Times of London. The British paper bars anyone who does not pay from reading its website, an action that has resascii117lted in a 90 percent plascii117nge in visitors.

Aboascii117t 31.4 million individascii117als visited NYTimes.com in Febrascii117ary, according to online research measascii117rement firm comScore.

It remains to be seen whether people will pay for digital news. Of the three dozen newspapers that have moved to some sort of online pay model, only 1 percent of readers have opted to pay, according to a recent stascii117dy by the Pew Research Centers Project for Excellence in Joascii117rnalism.
