The lecture tells us about two marketing strategies normally applied in business. One is to choose the right time，the other is to choose the right geographic location. Then the professor goes on to explain that by giving two examples. One is that a toy car company is going to sell their products to children,so they put out their commercial at the time when children are watching their favorite channel. Then the kids will ask their parents to buy for them after they watch it on TV. Another example is a boat company often publicizes their products near the coastal areas like ocean，lake，which is the right place to increase their sales. While on the other hand, if they do the advertising in the mainland, where there’s no river or water,they won’t achieve a competitive advantage.
