$1,000,000,000.

That’s how much money has been spent, since its release on October 28th 2007, on Guitar Hero III. That’s enough money to buy 1.3 million 16GB pay-as-you-go iPhones, 18 million Thrustmaster T.16000M joysticks, or 50,000 blinged-up Macbook Airs.

Of course, the whole thing is helped by the fact that the game cost about $90 when it was released, almost twice the price of a normal game, due to its plastic guitar peripheral. Expect sales of Guitar Hero World Tour and Rock Band, however, to eclipse this figure once again, due to their massive full-band instrument packs.
