Marketing

1. You see a gorgeous girl in a party, you approach her and say: "I'm rich, marry me."
That's direct marketing.
2. Your friend goes to a girl, points at you and says: "He is very rich, marry him."
That's advertising.
3. Girl walks up to you and says: "You are rich, will you marry me?"
That's brand recognition.
4. You say: "I'm rich, marry me." and she slaps you.
That's customer feedback.
5. You say: "I'm rich, marry me." and she introduces you to her husband.
That's demand and supply gap.
6. Before anybody says anything your wife arrives.
That's restriction from entering new market.
