The family business quickly grew and more of Mr. Feist's family became involved. The service department was now in need of another technician to help with the expanding repair business and soon hired a young man who was working in Harvey, ND.

Mr. Feist's son bought into the business and within a couple of years opened a location in Mandan, where another technician was hired fresh out of college. The business continued to grow, and over the years had many family members and other employees become part of the "Feist " family. They increased their product line to include such items as VCR's, Video Cameras and Video Disc Players, and setting up the first movie rental place in Bismarck. Always on the cutting edge of technology, the Feists introduced many new consumer electronic products to the area including Home Theater Systems, Laser Disc Players, Camcorders, High Definition TV and most recently 4k products.

In the mid 80's Feist Electronics began providing video production services. Mainly film transfers of 8mm or super 8mm, but expanded into video editing, tape duplications, video photo albums and transfers from many formats to DVD and other media, all services that are currently being provided today by Feist Electronics.

During the late 80's they combined the two locations in order to bring together a full staff that could serve customers more efficiently and effectively than ever before. This proved to be a good decision as they outgrew their location and moved into the space next door nearly tripling the amount of room for their business.

As the years went by, the Feist family decided it was time to retire from the business. So they sold it to the two technicians that had been hired nearly from the beginning. The two new owners, Daryl Rosenau and Clarence Sayler, moved the business to its current location of 225 West Broadway, where they still sell top quality televisions from Sony and LG, Blu-Ray and 4K DVD players, sound bars, surround sound systems, wall mount systems, antennas and many types of A/V accessories backed up with local repair, customer service, professional delivery, installation, wall mounting, setup and customer instruction.
