The Wall Street Journal has been a financial newspaper since its founding in 1889. Many newspapers that are called “journal” are unflatteringly nicknamed “urinal,” and The Wall Street Journal has been nicknamed The Wall Street Urinal since at least 1991.
 
Other nicknames of The Wall Street Journal include “Capitalist Bible” and “War Street Journal.”
 
 
Wikipedia: The Wall Street Journal
The Wall Street Journal is an American English-language international daily newspaper with a special emphasis on business and economic news. It is published in New York City by Dow Jones & Company, a division of News Corporation, along with the Asian and European editions of the Journal.
 
The Journal is the largest newspaper in the United States, by circulation. According to the Audit Bureau of Circulations, it has a circulation of 2.1 million copies (including 400,000 online paid subscriptions), as of March 2010, compared to USA Today‘s 1.8 million. Its main rival, in the business newspaper sector, is the London-based Financial Times, which also publishes several international editions.
 
The Journal primarily covers American economic and international business topics, and financial news and issues. Its name derives from Wall Street, located in New York City, which is the heart of the financial district; it has been printed continuously since its inception on July 8, 1889, by Charles Dow, Edward Jones, and Charles Bergstresser.
