Google Maps
Google Maps was started on February 8, 2005, and uses JavaScript, XML and AJAX. Its website works in almost any web browser or through mobile applications on platforms like iOS and Android. Google has a "Local Guides" program where anybody can write reviews and upload photos or videos of places, as well as make changes to the maps (such as adding new places or removing closed places). This is much like how a person can contribute to Google Translate or to Wikipedia and other Wikimedia Foundation websites.
