Google bought Dodgeball in 2005 and shut it down in 2009, replacing it with Google Latitude.
On August 7, 2014 the company launched Foursquare 8.0, the completely new version of the service which finally removed the check in and location sharing entirely, to focus entirely on local search.
As of December 2013, Foursquare reported 45 million registered users, though many of these will not be active users.
Foursquare 8.0 uses its own proprietary technology called Pilgrim to detect a user's location.
Pilgrim is able to guess a user's current location by comparing historical check-in data (previous users tacitly stating "I am here") with a combination of signals such as a user‘s current GPS signal, cell tower triangulation, cellular signal strength and surrounding wifi signals.
Recommendations are personalised based on factors that include a users check-in history, their "Tastes" and their venue ratings and according to their friends reviews.
