Technology
It is amazing how technology seems to be advancing at such a fast rate. It seems hardly any time since I begged my parents to buy me a Sony Walkman and now they are virtually antiques and MP3 players are all the rage. It seems that once we start to advance in a particular field things suddenly rocket for a while because consumers are interested and want something newer and better in that genre. Then something new come on the market such as an iPhone and everyone is talking about phones instead of music players for a while. I guess marketing is key and it is influencing more than we think.
