The social networking service known as foursquare, which launched in 2009, announced this week that it hit a whole new place value with its check-ins – billions.

foursquare said in its blog post that it had hit a billion check-ins on Tuesday, claiming it is a big number for a service that only launched two years ago.

The foursquare blog also wrote “….a billion check-ins was pretty cool. Thanks for helping us get there, and we look forward to the next quadrillion.”

The company celebrated the feat by creating a video with brilliant twinkling lights from around the world. The video is only: 56 long. I recommend you watch it in full screen because the effects are cool and it’s kind of fun. You will see the patterns as night settles over the globe and categories grow in brightness and fade on different continents.

The New York-based foursquare claims to have more than 10 million users with over three million check-ins taking place every day. If you do the math, it will take little over 333,333,333 days to hit quadrillion. Until foursquare reaches their targeted number, they plan to keep improving their service and to make cities “easier to use and more interesting to explore.”
