The most important factor that education is on its peak the level of education is increased day by day and people get more and more knowledge, now as we can compare the propaganda in the history and the th4e propaganda in the today modern world we can see a huge difference between today world propaganda and the propaganda on; last two or three decades. In past people were not aware of education much or as compare to the today world, so in past pro[against easily implement his or her propaganda on the public because in that time there no internet or the mobile phone but as we compare in the today world the education is very strong and peoplehave internet so they can search everything which thy want so it is not easily for the propagandist to implement propaganda on modern or today worldpeople , people are more likely to find out the reason of any happening or the news in the current affairs so if his propaganda in the news so they can easilyjudge that, hence we can say that propaganda as not strong as much as strong in the past.
