The newspaper cut off support to the apps for BlackBerry and the DealBook BlackBerry Reader on Monday, directing BlackBerry users to use the NYT mobile site instead.
"Currently, our mobile Web site offers a more complete New York Times experience than the NYTimes app native to your device," the NYT wrote in an announcement to its customers. "We've made the decision to consolidate our efforts and concentrate on delivering you the best possible experience through our mobile site."
It's yet another blow to BlackBerry maker Research In Motion, which continues to see a drop in sales and investor confidence.
A NYT representative told Reuters that the company dedicates its resources to products users are moving toward and that the BlackBerry app has had a "drop-off" in users.
But the publication may consider supporting a new app for BlackBerry 10, RIM's new operating system. BlackBerry 10 is expected to be released early next year.
In response to the news, RIM told Reuters it would "incorporate their feedback" as it prepares to launch BlackBerry 10.
The company has delayed the launch of the new OS, saying it hopes to bring a more complete product to market, rather than rush something out.
