As someone who owns four brands I can tell you that repetition in advertising is correct. The general public needs to be hit over the head numerous times with the same boring message over and over before they even look at the brand let alone try it.
I agree with your notion of repetition.
That said, Greta had Palin on for a good chunk of the first segment of her show Thursday night. After SP gave the repetitive-type answers we’ve come to expect from her, Greta asked her in terms of specific policy, what she would have said if she were giving the SOTU. Things to get the economy going. And SP did not deviate and did not get specific at all. Greta gave her an opening to drive a truck through and she didn’t take it. I am a big fan of SP (see my tagline) but I must confess, it disappointed me a bit.
Then again, maybe the gov was just having an off day!
