Bloomberg Businessweek, known until 2010 as BusinessWeek, is an American weekly business magazine published by Bloomberg L.P. Businessweek was founded in 1929, the magazine was created to provide information and interpretation about what was happening in the business world. It is headquartered in New York City. Businessweek was first published in September 1929, weeks before the stock market crash of 1929. The magazine provided information and opinions on what was happening in the business world at the time. Early sections of the magazine included marketing, labor, finance, management and Washington Outlook, which made Businessweek one of the first publications to cover national political issues that directly impacted the business world.
Businessweek was originally published to be a resource for business managers. However, in the 1970s, the magazine shifted its strategy and added consumers outside of the business world.Since 1975, Businessweek has carried more annual advertising pages than any other magazine in the United States.
Stephen B. Shepard served as editor-in-chief from 1984 until 2005 when he was chosen to be the founding dean of the CUNY Graduate School of Journalism. Under Shepard, Businessweek's readership grew to more than six million in the late 1980s. He was succeeded by Stephen J. Adler of The Wall Street Journal.
