Bandwagon technique: Encourages people to think or act in some way just because everyone is doing so. An example of this is the beats by dre head phones, simply because all the stars like The Kardashians and Nikki Minaj are seen with them on their head, people are thinking they are the it things and best out so everyone is jumping on the bandwagon.
Snob appeal: Technique to make people think or act a certain way simply because of high social status associated with the action of thought. An example of this technique is the sales of Mercedes-Benz Vehicles. They are selling luxury elevated cars that tell a lifestyle of class. If you have a Mercedes you must be doing things right in life.
