SAN FRANCISCO (Reuters) - Social networking services Facebook Inc and Twitter are coming to Google Glass, the wearable computer made by the Internet search company.

Google Inc announced on Thursday a half-dozen apps specially designed to work on its Glass devices. News network CNN, fashion magazine Elle, as well as online apps Tumblr and Evernote were among the half-dozen new apps for Glass unveiled during Google's annual developer conference in San Francisco.

Google Glass is a stamp-sized electronic screen mounted on the left side of a pair of eyeglass frames which can record video, access email and messages and retrieve information from the Web.

Google began distributing the devices last month to a limited number of developers, but it has yet to specify when a version will be available for consumers or at what price.

The futuristic-looking devices have been a common sight at the Google conference this week, with many of the attendees and staffers wearing Glass. But Google executives gave Glass short shrift during the more than three-hour keynote talks on Wednesday, barely mentioning Glass among the litany of new products and services discussed on stage.
