Oil and Gas Investor debuted 35 years ago with this August issue. Hart Energy, at that time pub­lisher of oil and gas trade titles such as the Western Oil Reporter, Drillbit and Rocky Mountain Oil and Gas Directory, had just moved from above the Greyhound bus station in downtown Denver to better accommoda­tions.

In a field of black-and-white, tech-fo­cused trade pubs, owner Don Hart imagined a sophisticated, glossy magazine with first-hand reporting in the oilfield and captivating field photography that would appeal to the busi­nessman in the energy investor community.

And so it was born. Oil and Gas Investor was like no other publication of its time. The goal remains the same today.

Naturally, a birthday begs a look back, if only to remind us from whence we’ve come. Executive Editor Leslie Haines takes a look at the publication through the years in this video. Meanwhile, Editor-in-Chief Steve Toon draws comparisons of then and now in his monthly column.
