Sale to BYU
On April 26, 2018, Brigham Young University announced it would acquire KUMT for an undisclosed amount. The university uses KUMT as a full-time outlet for its campus-run radio network BYU Radio. The university had originally planned to drop KBYU-FM's classical music format in favor of BYU Radio, but the plans were met with criticism by listeners. The purchase was consummated on August 31, 2018, at a price of $875,000. BYU Radio programming officially began airing on the station September 17, 2018. KUMT airs all BYU Radio programming except football and men's basketball. In 2019 KUMT officially became the flagship station for BYU women's soccer followed by BYU Baseball in 2020. As a result BYU Radio no longer streams those events on KBYU-HD 2. However they are streamed on the BYU Sports Radio app, and most are simulcast on ESPN 960.
