As there are several (startup) companies in this field I just looked up who is still around/got bought and what's there status:
GeoEye was merged into DigitalGlobe. Google had secured exclusive online mapping use of the GeoEye-1 satellite (Google Maps/Earth). Google bought the direct competitor Skybox for US$500 million in August 1, 2014. (http://en.wikipedia.org/wiki/DigitalGlobe , http://en.wikipedia.org/wiki/GeoEye , http://en.wikipedia.org/wiki/Skybox_Imaging ). There is also "Spot Image" (EADS/Airbus), NASA (and other US agencies), Sovinformsputnik (the Russian Federal Space Agency) and others.
