"Foursquare has seen phenomenal growth over usage of its service. This week, it announced that\u00A0it counted its 3 billionth check-in. Not bad for a service with just over 25 million users worldwide.\r\n\r\nTwo years ago, the location-based check-in service said it had experienced its biggest growth in history which was marked by more than 380 million check-ins, the Rally to Restore Sanity, and a single check-in from space. Now, 24 months later, the number of check-ins has increased exponentially -- the company recorded its 1 billionth check-in September 2011, just 9 months later after its 380 millionth check-in.\r\n\r\nLast September, the company stated that it had 2.5 billion check-ins counted. In that three month period, it averaged 167 million check-ins, or around 6.2 million per day. To get this number, TNW found the difference between November and September numbers and divided it by the days since (81) and that resulted in 6.2 million daily check-ins.\r\n\r\nIn its four-year history, the company has made some key improvements to its platform in order to bring more value to its users. No longer\u00A0just a check-in service where you tell your friends where you're at, it has integrated and innovated so that you can take advantage of the venue and places around you. Just recently, Foursquare introduced the Explore feature on its website sharing recommendations and before that, an integration with OpenTable for reservations at your favorite restaurants.\r\n\r\nIt has also done some remarkable things this year, which most likely helped raise its profile -- this summer, it partnered with Starbucks to help (RED) beat AIDS and received over 35,000 check-ins, resulting in a donation of $35,000 to the charity. And it also became perhaps the only location service to claim the title of having the farthest recorded check-in: Mars.\r\n\r\nWant to see what Foursquare looked like four years ago? Take a stroll down memory lane and you can see what a prototype of what it was going to look like.\r\n\r\nThe company has over 100 people on its team between its offices in New York, San Francisco, and London. To date, it raised over $71 million from Union Square Ventures, Jack Dorsey, Kevin Rose, SV Angel, Andreessen Horowitz, Chris Dixon, CrunchFund, Spark Capital, O'Reilly AlphaTech Ventures, and others. It is currently looking into raising $50 million more for its fourth round of funding.\r\n\r\nPhoto credit:\u00A0Pablo Blazquez Dominguez/Getty Images"^^<http://www.w3.org/2001/XMLSchema#string>
