What is the similarity between 1984 and society today?
George Orwell's '1984' (first published 1949) still holds a lot of significance for societies and people today. In its own day it was considered a 'visionary' and 'futuristic' novel, which posited how the world would be in years to come.
Indeed, we can say that many of Orwell's ideas (in particular with regard to totalitarianism and the tendency of modrn governments to want to 'control' citizens) in this work, were proved true-- societies, governments, carried out steps to curtail popular freedom/s and citizens' voices and protests, and systems of vigilance emerged that remind one of 'Big Brother' watching...
Even today, in the 21st century, over 60 years after the novel's publication, there are numerous ways that it is still relevant; whereby we can see how the soiety in the book and contemporary societies around the world, have many similarities-- for example, here are some common points:
1. State control-- various states and governments still continue to exert increasing vigilance and control on the public, on citizens, in various ways eg through the media, in monitoring opinion/s, in guiding and dictating how people live and interact.
2. Electronic intrusion and mind control-- even today, various people such as governments, large corporations/businesses etc, 'play' with peoples minds and also intrude into various aspects of their lives through electronic means; for example, look at so many advertisements today, which are based on how other people are able to obtain our private information and collect all sorts of data on us, to ultimately exploit or control us, and to affect our minds with some sort of 'brainwashing' at some level.
These are only some basic examples, am sure you can think up many more when you re-read the text of the novel and contrast it to our daily lives today. It would be right to say that Orwell's book is still 'relevant' to our situation.
I also hope the links below are somewhat helpful in clarifying things and guiding further.
