ImaHima was a mobile location-based social-networking service created in 1999 and shut down in 2006. [1] This service was launched by the Japanese company of the same name, founded by Neeraj Jhanji. [2] This Japanese name means "are you free now?" [3] This company pioneered the concept of sharing current status (location, activity, mood) among friends using mobile phones. Initially ImaHima started out as an "unofficial" [4] service but was later accepted inside the walled garden of the Japanese mobile carriers (NTT DoCoMo, [5] KDDI, Softbank). At its peak, ImaHima had over 500,000 users in Japan and was also made available in Switzerland and Australia. The service won a few awards including the coveted Prix Ars Electronica in 2001. [6] The fundamental patents for mobile checkin, status updates and location-based advertising pioneered by ImaHima were acquired by Facebook in 2013. [7]
