PR Newswire started out in 1954 as a vendor hired by companies and agencies to send out text press releases to the media. Today, PR Newswire is hired by corporations, public relations firms and non-governmental organizations to deliver news and multimedia content. Recipients include the media, consumers and investors who access the content via the Web, RSS, e-mail, satellite, equities terminals (such as Bloomberg and Reuters), and direct feeds into newsroom editorial systems. The headquarters are in Lower Manhattan, New York City.

Public corporations in the United States, United Kingdom, Canada, and other nations, use PR Newswire as a method of reaching the investment and financial news community with important news and announcements, thus achieving the standard of "simultaneous disclosure" required by financial markets and regulatory agencies.

The company has several brands and services that include ProfNet, eWatch, MEDIAtlas, MultiVu, U.S. Newswire, Vintage Filings, MediaRoom and MediaSense.
