Launched in February 2004, Facebook is a social networking service founded by Mark Zuckerberg with his college roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. Early investors include Microsoft and Hong Kong tycoon Li Ka- shing, through his namesake charitable foundation. Facebook’s US$16 billion initial public offering in May 2012 generated huge investor interest although the shares subsequently slumped in price.
Facebook apps for iPhone-iPad add free calls
Facebook allowed users on Friday to make free calls to friends at the leading social network using its application tailored for iPhones or iPads.
An updated Facebook “app” for the popular Apple mobile devices shows when friends are online and then gives the option of ringing them up by tapping an icon on the screen.
Calls are routed over the Internet using telecom service data plans or connections to Wi-Fi hotspots. Facebook introduced a version of the feature earlier this year in its messenger program.
Upgrades in the Facebook 5.5 app included a button designed to make it easier to “like” online content and post comments at the social network.
