It's fascinating to see how well Google has branched out. It started as just a search engine competing with Lycos, AltaVista, & Yahoo and yet they didn't just stop, they kept going. They built all these new services & products around their core product (search) and it's paid off tremendously. It's definitely something to model future companies off of. When you win the race, don't stop, keep running.
EDIT: To those saying they're playing the long game; Playing the long game doesn't make sense. The long game is being fully wired. By the time poor areas become economically important enough to be advertised to, they will have traditional telecoms servicing them.
