PennWell publishes 45 business-to-business magazines and newsletters, conducts over 60 conferences and exhibitions on six continents, and has an extensive offering of books, maps, directories and database services. In 2011 it acquired a data mapping company and also expanded its publications in the technology field.
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. 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. P.C. Lauinger remained in control of the company until his death in 1988; the company is now led by his son-in-law, Robert Biolchini.
