How do you feel about using real brands in your stories/poems/books? For example, instead of saying "I'm going to eat some instant noodles" you say, "I'm going to eat some ramen." Some people just alter the real brands name in some way but it's still recognizable. Is there a legal difficulty here, or do most people abstain from using real names so that people around the world are more likely to understand? Personally, I love it when people use real names in their books, it really increases the realism in it for me - especially for sci fi and such. However, as I'm writing my own story/novel I'm hesitant about it. What are your thoughts?
