WFIU

Local station WFBM-TV broadcast on channel 6, and its audio was at 87.75 MHz, close to WFIU's frequency.

Many early sets were not sensitive enough to prevent interference, resulting in viewers hearing WFIU while they watched WFBM-TV and a deluge of complaints to the university.

However, its owners, three men from Louisville, Kentucky, were run out of business by the saturation of small Bloomington with three AM and one FM stations and a new newspaper all entering the market within the span of several years.

They sold the physical plant and advertising contracts to Sarkes Tarzian, owner of station WTTS, and shut it down on January 5, 1950.
