Yes We Can

The change of medium to a video allowed for many contributing factors to help empower this speech even more than it was. The fact that you see a very powerful man, the president of the United States giving the speech through most of the video alone gives it an immense amount of power, and the fact that you see him, a face whom everyone knows, standing up and giving this speech along with others whom we've never seen before adds to the argument that yes we can, us together can. the additional music added and voice-overs help to keep the audience interested in order to hear the main points of the speech. And the written words are a way to visually point of key parts and important features of the speech that viewers should not miss.
