Know-How Exchange : Student Questions

As said in the title, i would like to know your opinion about what you think is "good" marketing, I have to give a paper for tomorrow about what is good marketing to my professor.. Of course i have some ideas and information and i don't want you to make my homework =). But actually, the professor asked us to be original in the way we find our information, I think posting this question in a forum, and have multiple opinions could be a gool start!

PLz leave your opinion about "what is GOOD marketing", it's really important and would be really helpful!

Thanks in advance,
