Says they put it out in 2009.
Weird, I never knew about this app in particular. If it was 2009 it was when they were trying different avenues to make money (before they decided on subscriptions)- or else at the time they couldn't make it free. I don't know. 2009 was when they made the Giant Bomb app too if I recall. This is probably just another hold over from that stuff, though. They were experimenting with a lot of stuff back then.
