Is the old new again?

Marketing is very important to get products flying out of supermarket shelves. Last week I went to the supermarket to get groceries. At home, when I has putting them in their right cupboards I noticed this big sign in a grissini package 'NOVITA - Gusto classico', which means 'NEW - Classic taste'.
If you stop a moment and think about it it's a quite ridiculous statement. I greatly suspect that they didn't even change the grissini receipt. Is there any law which obligates manufacturers to justify this grandiose statements?

I'm quite sure it wasn't the phrase that influenced me to buy the product, usually I look at a price vs my perceived value to make my choices. But if it was, without even noticing, I bow to the genial mind that conceived such package.
