Granite Broadcasting acquired KBJR at the end of October 1988, making it one of the company's earliest acquisitions. On December 14, 1997, KBJR's studios were destroyed in a fire late that evening. It left the air temporarily but managed to get back on-the-air the next morning cobbling together a makeshift workspace at its transmitter building. Two days later, the news operation moved in with PBS member station WDSE and sales and business operations moved to open office space at the U.S. Bank building in Downtown Duluth while master control remained at the transmitter. In April 1999, a spring ice storm swept through Duluth. The heavy accumulation of ice severely damaged KBJR's transmitting tower and, as the melting ice started falling off the tower, large ice chunks broke through the roof of the transmitter building flooding it with water and damaging much of the equipment inside. Master control operations were moved again using a temporary transmitter on WDIO's tower while KBJR's own tower and transmitter were replaced. In June 1999, it relocated to its current location in Canal Park.
