WIBM was first licensed on June 3, 1925[2] to Billy Maine in Chicago, Illinois as a portable broadcasting station.

However, taking advantage of the coincidence, in later years the station's Top 40 music record surveys were designed to resemble an IBM computer keypunch card.

They were commonly hired out for a few weeks at a time to theaters located in small towns that didn't have their own radio stations, to be used for special programs broadcast to the local community.

However, due to the difficulty of regulating "moving targets", in May 1927 the newly formed Federal Radio Commission warned that it would soon stop licensing portable facilities.

[6] Facing deletion, Carrell arranged for the station to be permanently moved to Jackson, Michigan.

[10] On June 30, 2016, WIBM changed their format from sports (which remains on WKHM-HD2 and W270CJ) to country, branded as "95.9 The Power Cow", simulcast on WKHM-HD3 and translator W240DG 95.9 FM Jackson.
