The telegraph made communication easy. Messages could be sent faster than ever with the cables allowing electricity to pass from state to state. It gave the Union a ridiculous advantage in the Civil War. When the Confederate discussed strategy with their generals all in the same tent, the President at that time, Abraham Lincoln had been camping in his office, reading letters sent through the telegram. From that position, he could get regular updates about the changes in the battlefield and change strategies to fit their needs and counter their enemies. They could be sent back at a blistering pace.
To the civilians, communication also became more convenient. Letters traveled faster without the need to be physical. News arrived earlier and got updated frequently. Just through Morse code and the telegram, technology has made life much simpler and faster. News from the war was quick to fall under the ears of everyone. And loved ones back home could also communicate with the soldiers more regularly as letters could be processed faster.
The Internet is a place where you can get information about politics and the different parties in it. Social media allows you to hear different political views. It is a platform that can help convince other people (or dissuade them) from supporting your political party. People are allowed to be more vocal on their political opinions, memes have the power to sway the tide between political candidates, and other times, they are just funny.
It is also a place where people in high positions like the President of America: Donald J. Trump can interact and vocalize his opinions or thoughts directly to the masses (both in and out of the United States). That does not always go well with people, but it is what it is. Social media also has videos of international summits or conferences to count for history. And drives in further the point: what gets uploaded on the Internet, stays on the Internet.
