As of this writing, there are several major mapping providers used on the Web and in mobile apps: Google, Microsoft, MapQuest (owned by AOL) and, of questionable quality, Apple. As of this writing, there are two major search providers: Google and Microsoft Bing. Notice that there is a lot of overlap.
Additionally, there are some secondary players in both markets. AOL still thinks of itself as a search engine, sort of, kind of, although its behaviour in that regard has been questionable for years, and has been schizophrenic: is it a search engine?
