Cartoon Network's Adult Swim programming division has been surprisingly Mac-friendly -- not only has it produced a number of great iOS games already, but its shows have included a number of Mac references as well (always in the service of comedy, of course). I guess it's no surprise that Adult Swim released a universal app of its own. Like many television apps, there are some extras, including a schedule of shows, and clock, weather and calendar features. But the real draw here is that you can watch full episodes of Adult Swim shows in the app, from Tim and Eric Awesome Show Great Job to Family Guy (reruns), Aqua Teen Hunger Force and, one of my favorites, The Venture Brothers.
And the best part is that the app is completely and totally free. If you're an Adult Swim fan at all, you'll definitely want to go get it off of the App Store right now. Great to see such a solid strategy from these guys on iOS -- I guess they definitely know where their audience is.
