What my classmates think about advertising VS Marketing

First off im using the opinions of three women from the class. That being said they are all fashion student funny isnt it? im Rebecca says that "advertising is most essential for sales". Shantay explains " Without advertising there will be no marketing". Maryann thinks " Advertising is key". Can sombody help me these three women have no idea what they are talking about before a bussiness advertises it must first market duh ladies if you werent so stuck on fashon commercials you would understand this concept. Did red bull when they first came out advertise on TV or did they not first give out free product on street corners and events then when they seen the demand people had for there product then and only then did they start to advertise on television. Please someone help these ladies they have hope. I guess i win battle over congradulations KINGZION.
