Check out this Google Maps Mashup I created which looks at Twitter mentions from across United States of Detroit Area Companies. The Detroit Area Companies which I added in this mashup are GM, Ford, Chrysler, Onstar, Compuware, Quicken Loans, Detroit Edison, Consumers Energy, Dominos Pizza, Little Caesars. 
You can make your Co. selection by clicking on the radio buttons at the side of the map and the map then animates thru the latest tweet mention of that company.
