Chen: BlackBerry Messenger can drum up $100 million

BlackBerry CEO talks wearables, BBM

BlackBerry believes it can make about $100 million from its BBM messaging service in the fiscal year beginning in March, CEO John Chen told CNBC on Wednesday from the International Consumer Electronics Show.

The company announced at CES that it would launch a BBM messaging app for Android Wear devices, such as smartwatches. Blackberry will seek to increase monthly active BBM users and make the service "more sticky" so that those users spend more time inside the app, Chen said in an interview on CNBC's "Fast Money: Halftime Report."

He also said demand is "very good" for the Blackberry Classic phone, a model that focuses on the company's traditional functionality and puts its physical QWERTY keyboard front and center.

On Wednesday, AT&T announced it would exclusively carry a newly designed Blackberry Passport with a 4.5-inch touch screen and touch-enabled keyboard that combines features of physical keys and a touch pad.

"I need to work on the distribution, and the AT&T announcement this morning helped us a lot about getting the phones to the consumers and getting them to the enterprise users," Chen said.

Shares of BlackBerry are up about 15 percent during the last three months.
