Public Relations is one of the oldest professions in world history. The modern history of public relations begins in the mid 1800 with a circus manager and entertainer called Barnum. It is said that Barnum was such a Master of Publicity and a Master of Showmanship, he promoted a European singer named Jenny Lind so successfully in the United States. Before she landed on the shores of America, she was a huge star selling out a stadium and nobody had even heard her sing a single note.
