PennWell Corporation is a diversified business-to-business publisher founded in 1910[1] and based in Tulsa, Oklahoma. It is owned by the British company Clarion Events.

PennWell publishes 45 business-to-business magazines and newsletters, conducts over 60 conferences and exhibitions on six continents, and also offers books, maps, directories and database services.[2] In 2011 it acquired a data mapping company and also expanded its publications in the technology field.[3]


The company, originally called the Petroleum Publishing Company and owned by Pennsylvanian Patrick Boyle, began in 1910 with the acquisition of a magazine based in Beaumont, Texas, called Oil Investors Journal; Boyle moved the publication to Tulsa and renamed it Oil & Gas Journal.[4][5] Boyle died in 1920, and was succeeded first by his son-in-law Frank T. Lauinger, and then, in 1932, by his grandson P.C. Lauinger, who led the Journal to increasing financial success, established a number of other petroleum-oriented publications, and acquired publications in the dental care field.[6] P.C. Lauinger remained in control of the company until his death in 1988; thereafter his son-in-law, Robert Biolchini, led the company[4] until 2015, when Mark Wilmoth was elected president and CEO while Biolchini became chairman of the board.[7]

In 2018, PennWell was acquired by Clarion Events, a British company owned by The Blackstone Group.[8] In 2019, Clarion sold several PennWell divisions to Endeavor Business Media.[9]
