What's great advertising ?

Do you know what it means by great advertising? As per Leo Burnett, "Good advertising does not just circulate information. It penetrates the public mind with desires and belief."

A Good Selling proposition

A great quote by Leo Burnett, "A good basic selling idea, involvement and relevancy, of course, are as important as ever, but in the advertising din of today, unless you make yourself noticed and believed, you ain't got nothing".
