How We Started

We started up in 1992, and we’ve been on an epic ride ever since. PowerPulse was originally founded by Jeff Shepard as part of Darnell Group, in the family home basement that was converted into a home office. From our on-demand FAX-based newsletter beginnings (remember those?!), it didn’t take long to recognize the potential power of the Internet. Initially called Power Electronics International in 1995 before being renamed, in the spring of 1999 PowerPulse.Net was born, launching the first daily news website for the global power electronics engineering community.

While Jeff is still involved as our Editor-in-Chief, and his wife Traci still leading marketing and business development, his son Paul, who drives the digital publishing technology, has since taken the reigns. PowerPulse truly is a family business. While the company name may have changed from Darnell Group to Opportunity Media, we’ve tried to stay true to our core beliefs and to deliver an exceptional experience for our community and subscribers. We owe a huge thanks to our community for joining us on this awesome journey, and we hope that you’ll continue to be a part of our story.
