Saw the Bankwest singing kittens ad recently and thought it was a nice approach. It is also interesting to note that they are using an informal voice throughout their other customer service channels too. So it is not just creative but IVR, online, etc. This integrated approach seems to be part of their overall positioning strategy to support their east coast expansion.
I don’t really care – I just liked the kittehs!
