Facebook is increasing its revenue from mobile with more users now accessing the social network via smartphones and tablets than from personal computers, but Wall Street remains unimpressed.

The company on Wednesday reported a $64 million profit in the fourth quarter of last year, a steep drop compared with $302 million 12 months earlier, while revenue grew 40 percent to $1.585 billion.

The New York Times said Wednesday it had fallen victim to hackers possibly connected to China's military, linking the attacks to its expose of the vast wealth amassed by a top leader's family.

The hackers have over the past four months infiltrated computer systems and snatched staff passwords, and their probing has been particularly focused on the emails of Shanghai bureau chief David Barboza, the newspaper said.

BlackBerry launched its comeback effort Wednesday with a revamped platform and a pair of sleek new handsets, along with a company name change as part of a move to reinvent the smartphone maker.

Canadian-based Research in Motion said it had changed its name to BlackBerry as it launched the BlackBerry 10, the new platform aimed at helping the firm regain traction in a market now dominated by rivals.

Fresh from unveiling detailed online maps of North Korea, Google on Wednesday touted studies showing that Internet Age navigation tools boost the economic engines of nations.

The global "geospatial industry" brings in $270 billion in annual revenue and companies in the sector pay more than $90 billion in wages each year, according to a report by economic consulting firm Oxera.

As much as I like Google Docs for word processing and spreadsheets, I find the online software clunky at times. So I was skeptical when I heard Microsoft is trying to sell its new version of Office as an online subscription.

I was pleasantly surprised to learn that the subscription gets you the same software you'd get buying it at a retail store. In fact, I'm using the new Office 2013 to write this review, and it feels as smooth as the customized version of Office 2010 I regularly use.

It's the moment of truth for BlackBerry maker Research in Motion.

The Canadian company Wednesday will officially launch the BlackBerry 10, an effort that some see as the company's last, best chance to remain a player in a smartphone market it once dominated.

WhatsApp's mobile messaging service used by hundreds of millions of customers worldwide breached privacy laws in at least two countries, a joint Canadian-Dutch probe concluded Monday.

The California-based mobile app developer violated "certain internationally accepted privacy principles, mainly in relation to the retention, safeguard, and disclosure of personal data," Canada's privacy commissioner and the Dutch Data Protection Authority (CBP) said in a joint statement.

Apple said Monday it was releasing updated mobile software for the iPhone and iPad which makes it easier for users to get on high-speed networks.

The iOS 6.1 version, which updates the one released last year, includes Apple's own maps program which drew scorn from users because of numerous glitches, and which Apple has pledged to fix.

South Korea's Samsung Electronics said Tuesday it had bought U.S. medical imaging firm NeuroLogica, as it seeks to explore new growth sources by expanding into the health sector.

Samsung did not disclose the value of the deal but said it had bought a full stake in the Massachusetts-based firm, which makes medical devices including CT scanners.

Weeks after its chairman Eric Schmidt's secretive visit to North Korea, Google has rolled out a detailed map of the isolated state that even labels some of its remote and infamous gulags.

Until now North Korea was pretty much a blank canvas to users of Google's "Map Maker", which creates maps from data that is provided by the public and fact-checked in a similar process to that used by Wikipedia.
