     The rise of multinational corporations (跨国公司), global marketing, new communications

technologies, and shrinking cultural differences have led to an unparalleled increase in global

public relations or PR.

     Surprisingly, since modern PR was largely an American invention, the U.S. leadership in public

relations is being threatened by PR efforts in other countries. Ten years ago, for example, the

world's top five public relations agencies were American-owned. In 1991, only one was. The

British in particular are becoming more sophisticated and creative. A recent survey found that

more than half of all British companies include PR as part of their corporate (公司的) planning

activities, compared to about one-third of U.S. companies. It may not be long before London

replaces New York as the capital of PR.

     Why is America lagging behind in the global PR race? First, Americans as a whole tend to

be fairly provincial and take more of an interest in local affairs. Knowledge of world geography,

for example, has never been strong in this country. Secondly, Americans lag behind their European

and Asian counterparts (相对应的人) in knowing a second language. Less than 5 percent of

Burson-Marshall's U.S. employees know two languages. Ogilvy and Mather has about the

same percentage. Conversely, some European firms have half or more of their employees fluent

in a second language. Finally, people involved in PR abroad tend to keep a closer eye on

international affairs. In the financial PR area, for instance, most Americans read the Wall Street

Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London

and The Economist, publications not often read in this country.

     Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable News Network).

Turner recently announced that the word "foreign" would no longer be used on CNN news

broadcasts. According to Turner, global communications have made the nations of the world

so interdependent that there is no longer any such thing as foreign.
