Who does GIS?

Is ESRI now synonymous with GIS?

When you visit the front pages of the major vendors websites there is an acronym that seems to be missing from most – GIS.

Autodesk has no mention of GIS or Geo (although a search does offer numerous entries deeper within the site)
ESRI heads the page with GIS and Mapping Software
Intergraph uses Geospatially Powered Solutions
MapInfo has coined Location Intelligence, of course the company name, while it lasts, does rather eloquently describe what they do.

I suppose the terminology reflects the language spoken by each company’s customers. In government it is Geographic Information, in infrastructure and utilities it is Geospatial and in the business sector it is Location Intelligence.
