2. History

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hosted at GTE Labs ( site no longer active), which was at the time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 KDnuggets 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 and cut salaries and work hours for all employees, including Gregory. The extra time and reduced salary motivated Gregory to put the first ads to support his work on KDnuggets.

was acquired by Xchange
in April 2000, and Gregory worked for Xchange for about a year as a Chief Scientist, Analytics. During that time Xchange market value reached $1B (briefly), and then fell almost to zero.
Gregory 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.
