It's been damned popular for a damned long time, but Angry Birds' numbers don't appear to be dwindling at all. As Mashable reports, 30 million people play the portable game each day, logging over 300 million minutes of gameplay. Each day!
That's 208,333.3 days of Angry Birds played for each day of real time (or, as the article points, out, 109.5 billion minutes per year). There is a lot of fun math to be done here, but the upshot is that no one seems to have gotten sick of Angry Birds, and the game's momentum doesn't show signs of slowing down.
For my part, I haven't played Angry Birds in months. But now I'm feeling like I'm left out of the zeitgeist.
