KDnuggets was started by Gregory Piatetsky-Shapiro in 1993 as a way to connect researchers attending the KDD-93 workshop on Knowledge Discovery and Data Mining (organized by Gregory and others at AAAI-93 in Washington, DC).

With the appearance of World Wide Web and Mosaic, Gregory Piatetsky-Shapiro and Chris Matheus have created a website called Knowledge Discovery Mine hosted at GTE Labs ( site no longer active), which was at the time the second site in the world covering data mining and knowledge discovery field.

While Gregory was at GTE Labs, the newsletter was published as "Knowledge Discovery Nuggets". It served as an unofficial publication of KDD workshops (started by Gregory Piatetsky-Shapiro in 1989), and helped them to grow and become conferences.

When Gregory left GTE Labs in 1997, he created site, with "KDnuggets" standing for Knowledge Discovery nuggets, (conveying the mission of covering the field with short, concise "nuggets" of useful information), and moved the Knowledge Discovery Mine to

Gregory was working from 1997 to 2000 as a Chief Scientist for Knowledge Stream Partners (KSP), which were providing data mining and customer analytics consulting to major banks and financial institutions, and editing KDnuggets late at night after work.

When Y2K crisis caused most of KSP to freeze any future projects (including any data mining projects), KSP lost most of its revenue and cut salaries and work hours for all employees, including Gregory. The extra time and reduced salary led Gregory to put the first ads to support his work on KDnuggets.

KSP was acquired by Xchange in April 2000, and Gregory worked for Xchange for about a year. He left Xchange in May 2001, during the collapse of the dot com bubble, and has been publishing KDnuggets as an ad-supported site since then.

Another popular feature is Cartoons, which take a humorous look at Data Mining and Data Science.

Here is KDnuggets Feb 2014 Valentine's Day cartoon: Cartoon: Data Scientist Valentine Day Prediction:
Data Scientist: "Sweetheart, my neural net predicts that you and I are 98.9% compatible. Will you be my Valentine?"

KDnuggets also keeps a large directory of current events on Business Analytics, Big Data, Data Mining, and Data Science, including:

KDnuggets also offers a free Data Mining Course - the teaching modules for a one-semester introductory course on Data Mining, suitable for advanced undergraduates or first-year graduate students. The course, created by Gregory Piatetsky-Shapiro and Prof. Gary Parker, was funded by a grant from W. M. Keck Foundation and Howard Hughes Medical Institute, and is freely available on the web.

In November 2009, KDnuggets added blog-style, daily publication and switched to a custom PHP-style platform that Gregory wrote. With the continued growth in visitors and popularity, KDnuggets converted most directory and news pages from 2013 forward to WordPress and switched to publishing using WordPress platform in Jan 2014.
