The Angry Birds francise is hugely popular, but a less-known fact is that it was basically a copy of various other flash games found around the internet. The developers of Angry Birds basically created a brand around their game with an accompanying storyline and combined this with excellent customer support that listens to their users and updates the game accordingly.
The animated video above is an example of this story, that is created alongside the games they release. This particular video is an introduction their new version of the game 'Angry Birds Space' and will even be broadcast on the popular children's TV channel Nickelodeon (very, very smart move!). I think that this kind of brand identity/narrative can be invaluable towards the success of an app, especially in the crowded and continuously expanding virtual app marketplace.
