Explanation: Barack Obama was first brought into office in 2009 and has held the position for the last six years. There have been forty-five presidents of the United States, but prior to him, they had all been white. A new comer to the post with many disliking him, this speech was pivotal, an opportunity to assert his authority and to assure the people of America that he was not just suitable for the job but also a visionary president. Obama managed this by using a variety of paralinguistic features, far more than used normally in speeches, throughout the presentation to keep his viewers interested and engaged. Over 1.8 million people in Central Park, New York watched his performance as it was broadcast across the globe.
