I'm not sure that's an entirely accurate description. At the very least, it seems misleading to characterize it as regular advertising. The channel "internetexplorer" on Youtube describes it as "created by Microsoft Singapore, dedicated to all anime fans worldwide in celebration of Anime Festival Asia (AFA) 2013". If anything, it sounds like it's at best like those special commercials that some companies do during the Olympics.
Still pretty cool, though. And I'd probably watch that anime, especially if it was made by a third party and included the other
Browser/OS-tans.
