[ Celebrities ] Open Question : Why are celebrities like Jennifer Aniston “propped up” so much by Hollywood? is it a conspiracy?

I mean i have looked even via search engine on Yahoo to see about questions on “Why people think Jennifer Aniston is so beautiful, hot, sexy, etc?” and could not believe how many questions there were about this. and why she is so popular and liked, etc? she has not hardly any personality, but she has been treated like she is some type of media queen since the middle 1990s, but WHY?
