Eight years ago, Google bought a cool little graphics business called Keyhole, which had been working on 3D maps. Along with the acquisition came Brian McClendon, aka "Bam", a tall and serious Kansan who in a previous incarnation had supplied high-end graphics software that Hollywood used in films including Jurassic Park and Terminator 2. It turned out to be a very smart move.

Today McClendon is Google's Mr Maps – presiding over one of the fastest-growing areas in the search giant's business, one that has recently left arch-rival Apple red-faced and threatens to make Google the most powerful company in mapping the world has ever seen.

Google is throwing its considerable resources into building arguably the most comprehensive map ever made. It's all part of the company's self-avowed mission is to organize all the world's information, says McClendon.
