Answer:
A Celebrity is someone who has achieved a level of notoriety usually with ties to some form of media and strictly to that type of media. A cultural icon is someone who has achieved some level of notoriety as with a celebrity. but the main difference is that cultural icons has a more positive connotation and did something to warrant a change for the culture they may represent. In terms of becoming a celebrity, i do believe you need some level of talent in that you need to do something to achieve some kind of notoriety more recently this has been fairly easy ( especially to those who use you Tube as their outlets) and if you make the right kind of video.
