History
The station signed on for the first time on October 14, 1954, as WIAN, operated by the Indianapolis Public Schools, with the license held by the Board of School Commissioners. At first, it was powered at only 120 watts. The station offered classroom instruction and some student programming. In the 1960s, the station increased its power to the current 10,000 watts.

After years of operating at low power and limited hours, it expanded its hours and programming through a partnership with The Fine Arts Society of Indianapolis in which the Society broadcast classical music, apart from some hours devoted to educational programming. This gave WIAN enough hours to become a charter member of NPR in 1971.

IPS sold the station to Metropolitan Indianapolis Public Broadcasting in 1988, and on March 15, 1988, it changed its call sign to WFYI-FM. Over time, the amount of classical music was decreased as the station added more news and informational programming.

WFYI is the home base of the health news service Side Effects Public Media.
