Illinois State University's college radio began broadcasting via carrier current on 106.1 FM and 540 AM on March 18, 1981.
WZND has had many locations on campus. Its original location was in Cook Hall in 1981, but moved to Old Union in 1985. In the spring of 1994, WZND relocated to the lower level of Fell Hall and remain there. A studio in the station is named after the founder of WZND (formerly WILN), Ruth Yates. In 2001, WZND became known as Z106 until 2010, when it again used its call letters WZND as its branding. As Z106, WZND had a dual format, playing three days of alternative music and three days of hip-hop. This continued until 2010, when it adopted its current format.
On September 27, 2011, the Illinois State University Foundation took over the 103.3 FM frequency from WEWT-LP, allowing Illinois State University's college radio station to be heard outside the Illinois State campus for the first time in its history.
