In 1976, the station moved to King Hall, and in February 1977, WEMU began to feature a primarily jazz format. Later that year, in October 1977, WEMU changed to its current 89.1 FM frequency. The next major addition came on April 7, 2004, when WEMU added digital broadcasting.[2] Located online at WEMU.org, the station streams live 24 hours a day.
