Moody's Corporation, often referred to as Moody's, is an American business and financial services company. It is the holding company for Moody's Investors Service (MIS), an American credit rating agency, and Moody's Analytics (MA), an American provider of financial analysis software and services. Moody's was founded by John Moody in 1909 to produce manuals of statistics related to stocks and bonds and bond ratings. Moody's was acquired by Dun & Bradstreet in 1962. In 2000, Dun & Bradstreet spun off Moody's Corporation as a separate company that was listed on the NYSE under MCO. In 2007, Moody's Corporation was split into two operating divisions, Moody's Investors Service, the rating agency, and Moody's Analytics, with all of its other products. It was included in the Fortune 500 list for the first time in 2021. History of Moody's Moody's Corporation traces its history back to two publishing companies established by John Moody, the inventor of modern bond credit ratings. It was first published in 1900 by John Moody, nine years before he founded Moody's Corporation. Initially called Moody's Manual of Industrial and Miscellaneous Securities, it was later superseded by Moody's Manual of Railroads and Corporation Securities, then by Moody's Analyses of Investments. In 1900, Moody published his first market assessment, called Moody's Manual of Industrial and Miscellaneous Securities, and established John Moody & Company. The publication provided detailed statistics relating to stocks and bonds of financial institutions, government agencies, manufacturing, mining, utilities, and food companies. It experienced early success, selling out its first print run in its first two months. By 1903, Moody's Manual was a nationally recognized publication. The 1907 financial crisis fueled several changes in the markets, including the creation of the Federal Reserve System. Meanwhile, Moody was forced to sell his business, due to a shortage of capital. Moody returned in 1909 with a new publication focused solely on railroad bonds, Analysis of Railroad Investments, and a new company, Moody's Analyses Publishing Company. In 1962, Moody's Investors Service was bought by Dun & Bradstreet, a firm engaged in the related field of credit reporting, although they continued to operate largely as independent companies. By the late 1990s, Moody's superior performance compared to its parent company brought investor pressure to separate the businesses. In 1998, Dun & Bradstreet sold the Moody's publishing business to Financial Communications (later renamed Mergent). In December 1999, Dun & Bradstreet announced it would spin off
