This document discusses the history and development of Arc2Earth, a company that began by providing an overview of ArcGIS capabilities but then expanded into building bridges between ArcGIS and open source GIS tools. Key developments included the birth of Arc2Earth in response to Google's entry into the GIS market, adding more functionality over time, the release of Arc2Earth Sync to connect ArcGIS data to the cloud, and plans to further integrate with open source tools which have grown in popularity.
