The United States government turned off the function of Selective Availability in May 2000, being able to limit the exactness of GPS signals for individuals. Within 24 hours, Dave Ulmer put Geocaching.com for the first time and uploaded its coordinates on the Internet. Not more than three days, two individuals utilized their own GPS receivers to find the container and told their experiences on the Internet. Four months later, Jeremy Irish set out the website of Geocaching.com as an enlisted spot to back the love. He was soon participated by Elias Alvord and Bryan Roth, who he worked with in his physical job at an ending 90's dot-com era startup. The three men got inspiration from the approaches in which location-focused technology could develop outdoor recreation.
