The recent hacking of Associated Press' Twitter account once again raised questions over the security of social-networking sites.

Earlier this week, cyber criminals hacked into AP's official Twitter account and posted a false tweet reporting explosions at the White House on Tuesday.

Facebook's soon-to-be-launched new mobile application `Home' is expected to generate a major opportunity for brands and retailers.

Social-networking giant Facebook's free voice calling service has finally become available at iOS devices in the U. K.

The free service can be accessed via the Facebook Messenger app for iOS-based Apple iPhone and iPad. Users can see a newly added "free call" button in the list of options on the app, which they can use to make calls to any of their friends and relatives mentioned in their Facebook contacts.

Micro-blogging site Twitter on Wednesday announced the launch of a new, uniquely tailored app for Windows 8 and Windows RT devices.

Popular social-networking site Facebook on Thursday gave a major facelift to its home page, referring to the new design as the groundwork for building the best personalized newspaper.

Reporting Facebook's 2102 fourth-quarter earnings during a recent conference call with financial analysts, the social network's CEO Mark Zuckerberg said that the mentioned quarter witnessed a 40 percent year-on-year increase in the company's revenue; with the number of daily mobile users surpassing daily Web-user numbers for the first time ever.

Popular micro-blogging site Twitter is reportedly on the verge of launching its own hosted video service called Vine.

AllThingsD cited anonymous named sources stating the Vine app, which will be available in the App Store, could arrive as early as Thursday.
