Google, Yahoo!, Microsoft, Michelin, Yandex and a lot others bought their data from various providers. They are usually named on the specific map and there isn't only one provider.

or

If you want free to use map data you can take a look at http://www.openstreetmap.org/ .

If you want free satellite map data then it's more complicated. This looks promising: http://worldwind.arc.nasa.gov/java/ .
