Apple don't spend as much on marketing as, say, Samsung when it comes to selling their phones but they're always quick to highlight just how innovative they are. As a result, Apple has sold over 600,000,000 iOS devices (namely the iPhone, iPad and MacBook).

The market-leading company has pioneered digital apps and music through the iTunes store, but their iOS devices are also pre-loaded with crowd-pleasing services that make life easier and much more fun. As such they've leap-frogged over Coca-Cola and resisted strong competition from rivals Google.

Interbrand's global chief executive Jez Frampton stated: "Every so often, a company changes our lives, not just with its products, but also with its ethos. Few brands have enabled so many people to do so much so easily, which is why Apple has legions of adoring fans."

"From our perspective, Apple's internal brand strength has remained steady. Chief executive Tim Cook has assembled a solid team that is aligned around the Apple vision, which has allowed them to deliver against the promise time and time again."
