The rollout began in October 2013, but many people who had Graph Search were not given immediate access to this feature. In late September 2013, Facebook announced that it would begin rolling out search for posts and comments as part of Graph Search. Facebook announced plans for a future mobile interface and the inclusion of Instagram photos. The feature has been released only to limited users, with a slow expansion planned. Company reports indicate that the service launched to between tens and hundreds of thousands of users. The Graph Search Features was launched in Beta January 2013 as a limited preview for some English users in the United States. The feature was developed under former Google employees Lars Rasmussen and Tom Stocky.
