The New York Post has gone from showing iPad users visiting its Web site an ad promoting its iPad app to blocking access altogether.

[ad#Google Adsense 300×250 in story]The online version of the newspaper will no longer allow iPad users to see any content. When you visit the Web site now, you are redirected to a page that reads in part:

“Thanks for coming! NYPOST.com editorial content is now only accessible on the iPad through the New York Post App.”

The app, available on the App Store, costs $1.99. Subscriptions through the app cost $6.99 for one month, $39.99 for six months, and $74.99 for a year.

The Web site is still accessible using the iPhone even though the company also has an iPhone app.

AppleInsider reports that nypost.com is still available on iPad browsers other than Safari.
