UBank Proving a hit on YouTube

Refusing to follow the expected conservative marketing approach expected from a Bank, NAB has turned to Twitter, FaceBook and You Tube to launch it's start-up online and phone based banking brand, UBank - to lure customers who are allergic to bank branches.

Using humour the two-minute information videos, called Money Box, tackle issues such as consumerism and the global financial crisis - with very low key reference to NAB (in fact, you really have to strain your eyes to see the logo at the end).

How effective do you think this form of promotion is? Is using like media ie web-based to attract customers to a web-based service, an effective way to promote the brand?
