I think that a good name is "propaganda", especially when the information is of political relevance.
In the past (and to some extend present) some totalitarian or non-democratic states used propaganda to shape public opinion.
Explanation:
On March 5, 1770 the dreadful day came. A mob of people went in front of the Customs Office in Boston Massachusetts and started to throw stuff and give insults at the soldiers. As a result to this so-called harassment the soldiers fired on the crowd. The first to die was an African-Amercan man named Crispus Attucks.
The protestant reformation began as a criticism of the Catholic Church's decadence and views of purgatory as well as many details in scripture. As people began to gain more interest in objects from Biblical history, explorations would become opportunities to discover lost artifacts, points to convert nonbelievers and to feed the thirst for knowledge.
