This Thai commercial was published on 9/11 only a week ago and already has eight and a half million views on Youtube. It's so good I'm going out to buy a USB Internet connection from True irrespective of whether it is a better deal or not than its competitive mobile and internet data carriers.
From time to time, Thai advertising is easily the best in the world.
I can tell you from experience that it's less about strategy than having something important to say. I've talked about this in the past.
