The format was "Fine Arts and News."[3] The reference to fine arts included classical music, opera and other musical genres not found on commercial radio. KWMU also used ABC Radio News for audio clips during newscasts.
In 1983, it was the first radio station in St. Louis to play music from compact discs. A year later, it became the first radio station in the United States to broadcast Ambisonic programs.
In 1992, the station increased its effective radiated power to 100,000 watts. In 1995, the station eliminated the remaining weekday music programs and moved to an all-news and talk format, except for a few specialty shows on weekend nights.
KWMU started using HD Radio technology to broadcast in 2006. In the fall of 2008, the station added a second digital stream, KWMU-2 The Gateway (Now Jazz KWMU-2), on its second digital subcarrier.

In the spring of 2010, the station added a third digital subchannel, Classical 90.7 KWMU-3, a 24-hour classical music service. Both stream live on the Internet.
On September 10, 2009, KWMU rebranded as St. Louis Public Radio (STLPR). Its website switched to a new address: stlpublicradio.org.
