Public Relations had developed as a matured and important profession when the World War II started. It had vast opportunities to grow with the invention of the radio and sound films and development in the techniques of printing. The effectiveness of public relations techniques in communicating with different sections of the public, in changing the public attitudes and winning support for a cause, an issue or an organization were recognized and appreciated. “Fortune” magazine, which had first taken note of the emergence of public relations in 1938, conduct a survey on PR in 1949. The report which was published in May issue that year stated that business in the US was still in trouble and that only good Public Relations, which denoted good performance, properly understood and appreciated, could assure its future.
During that time, PR had become an area of study in university education. The American Journals, Public Relations News and PR Journal started publication in 1944. The Public Relations Society of America was set up in 1948. The Hiroshima and Nagasaki bombing set world leaders thinking about the need of a better understanding and humane approach to global issues. Following this, the United Nations was set up in 1945 and its charter made the human being the axis, by reaffirming its faith in human rights and in the dignity and worth of the human person.
The UN declaration of faith in human rights has been adopted in its International Code of Ethics by the public relations practitioners of all the member countries, including the International Public Relations Association (IPRA).
