Software is a fast-changing environment, and very few products have the longevity of Esri.  The Esri Chest Agreement has become a mainstay of the Chest portfolio, quickly rising in prominence to become a very popular GIS Chest Agreement.  Many institutions subscribe through Chest to ArcGIS, with uses varying from Archaeology to Zoology and many things in between.  2017 saw the Agreement renew for a further three years, it'll be in its 27th year by the time the next renewal comes around!
