I know people have talked to death about this book, some people like some people hate it. Personally I liked it and will probably watch the movie when it comes out later, even though its hugely differant from the book. My question is how on earth was the writer able to fit so much pop culture stuff into this book without getting into trouble with the property holders? He referances all kinds of games, movies, music and series. Is there some kind of copyright loophole or something? Did they have to get special permission for this stuff? I'm interested in writing stories that referance things I like, but I'm worried off getting sued.
