Censorship is hiding the display of things and implementing surveillance on items that are considered “bad.” When taken into thought, there are endless amounts of items that may be censored. For example, when the government withholds information, things such as websites and social media. The difference between a challenged and banned book is that challenged books are an attempt to remove or restrict materials and banned books are the removal of the materials. An example of a book is 1984 by George Orwell because of the pro-communist ideals which also included explicit sexual matter. Fahrenheit 451 may be banned or challenged since one of the books that were burned in the novel is the bible.
