5. Submission doc.: IEEE 11-10/1033r0 Large Market Opportunity Juniper Research published a report which said the market for location-based services (think mobile check- in games like Foursquare, social networks like Loopt, location-enabled apps like Google Maps, etc.) will bring in revenues of more than $12.7 billion by 2014. Frost & Sullivan estimates that mobile advertising alone will generate $2.4B by 2015. Slide 5Russ Markhovsky, InvisiTrack, Inc. July, 2011
