"[Nasdaq](https://www.nasdaq.com/)" was initially an acronym for the National Association of Securities Dealers Automated Quotations. It was founded in 1971 by the National Association of Securities Dealers (NASD), now known as the Financial Industry Regulatory Authority ([FINRA](https://www.finra.org/)), with the goal to provide financial services and operate stock exchanges.

On Dec. 4th, 2018, Nasdaq announced it had acquired [Quandl, Inc.](https://www.quandl.com), a leading provider of alternative and core financial data. Quandl was founded by Tammer Kamel in 2012, with goal of making it easy for anyone to find and use high-quality data effectively in their professional decision-making. In 2021, Quandl was replaced by [Nasdaq Data Link](https://data.nasdaq.com/).
