Fahrenheit 451's appeal to audiences is the striking resemblance to our culture today.
HEALTH: Today, the news reports the potential of a kiosk that can help diagnose a person's problem is possible. This is comparable to the machine that went inside Mildred and sought out the problem of her health in the first chapter.
BOOKS: The written word on paper is slowly fading. Banks give people the ability to use their phones to scan in a check. Companies use email to send bills. The Nook and the Kindle as well as other eReaders are starting to replace the need for novels. Although words are still a great part of our society, the traditional book is fading. This is similar to the fictional culture in that they burned all books... but on purpose.
MEDIA: Mildred's parlor walls and seashells in her ears are strikingly similar to the entertainment industry's increasingly large televisions and ear buds for the iPod. What's more, these have almost the exact same effects in both cultures: the more that television is watched and the more that ideas are forced into the heads of consumers, the less those consumers think on their own.
The fact that this book was written in the late 40s, early 50s culture is even more frightening. That Bradbury could create a dystopia that has features of it coming true is scary! But, it is also a sound warning to readers to help them keep thinking. So consider two more areas of comparison to today's culture: education and transportation. You might be surprised what you find!
