You have just launched "add on" service/facility/function to your flagship product and your job is to entice user with this just launched "add on".
Just launched means you can't make tall claims such as "Number 1", "Fastest selling", "Most sold", etc.
Here is what Apple does : -
This advertisement was for newly launched 'gift card' facility for iPhone 3G. I've underlined the interesting part in 'RED' in the advertisements = "Talked-about".
Now, how can anyone dispute 'Most talked-about' claim?
Lesson: When you can't make objective claims, make subjective claims that no one can dispute!
iPhone- surely has the buzz, but not the 'Gift card'. So you try to steal the buzz of iPhone and pass it on to the 'add on'. By reading this adverstisement you don't know - 'Much talked about' is about the iPhone or the 'Gift card'. I'm sure not many talk about the 'Gift card' - Pleazzze...there is never a buzz about 'Gift cards'.
Isn't very smart and simple communication? At the same time making 'indisputable' tall claims which most users don't realize.
