"If you look up the definition of news in the dictionary, it isn't what you watch on TV"

This quote by Val Kilmer is a commentary on the state of contemporary news media. He is recommending that what exists on tv as news is not always what the dictionary would specify as news. This suggests that the news we view on tv is not constantly precise or unbiased. It might be argued that news media has actually ended up being more focused on entertainment than on offering accurate info. Kilmer is recommending that news ought to be more than just a kind of entertainment, but must instead provide trusted information. He is encouraging viewers to search for the definition of news in the dictionary and to compare it to what they watch on tv. This is a pointer that news should be a source of reality and not just a form of entertainment.
