NEW YORK -- New York Times Co. said Thursday it would put up its long-awaited paywall at NYTimes.com on March 28 in the US and around the world.

The company launched digital subscriptions in Canada Thursday to "fine-tune the customer experience" before the wider rollout.

For customers who do not subscribe to the print paper at home, NYTimes.com and a New York Times SmartPhone app will be priced at $15 a month.

All NYTimes.com users can see 20 articles a month for free; after that, they will be asked to pay for site access.

Readers who come to the site through links provided by blogs, social media or search engines will be able to see individual articles, even beyond the 20-story limit.

However, the company said, "for some search engines, users will have a daily limit" of free article links.

The homepage and all section fronts at NYTimes.com will stay free at all times.

In recent trading shares of New York Times Co. were up 3.4 percent.
