PennWell is celebrating its 100th anniversary this year. As our cover illustrates, the history of the company is deeply rooted in the oil business. In 1910, P. C.Boyle, PennWell's founder, bought the Oil & Gas Journal (then named Oil Investors' Journal), renamed it, changed its frequency from semimonthly to weekly, and moved the company to Tulsa, OK where it is headquartered to this day. Legend has it that P.C. Boyle was a spectacular oil scout during the 1880s, roaming the oilfields on a black horse, scouting news and drilling activity.
