In Ancient times very few people could read or write. To share information people could talk to others one by one. While that is often the best way, it takes a long time to tell anyone about the news or message. The other way to share information or messages more quickly was to get everyone together and have a speaker get up in front and tell everyone what needed to be told. That was the best method during that time in history. But, since the advent of the printing press, then later newspapers, radio, television, and now the Internet, the methods of sharing information has exploded.
