What’s cool about this is that they’ve anticipated the user’s context within the browser — here, they know exactly what warning Firefox will display and where it’s located — so they’re able to tell me exactly what to do by pointing to something that’s outside of their actual webpage. Pretty nifty.
Coincidentally, Vizio used a similar device in their recent Super Bowl ad where they used an arrow to point to the brand logo that’s typically positioned right below the screen on tv sets. Truly outside of the picture box. It’s like breaking the fourth wall!
Oh really, AT&T? You want me to switch to your internet service but I can only view your offer site in IE? Awesome. Not like that limits your market or anything.
