In January, 2013, KBBM changed their format from modern rock to sports and was now branded as "Sports Radio 100.1 The Fan".
In October that same year, the station began simulcasting on the previously country-formatted KZJF 104.1 FM, in a process of moving the sports format to KZJF's weaker signal. KBBM later split from the simulcast and is stunting with Christmas music and branded as "Santa 100.1". At 10:01 am one day later, the station switched its format from Christmas music to country, titling itself as the 100.1 Nash FM, much like other Cumulus-owned country music stations. This is now the second station owned by Cumulus to launch "Nash FM" as a newer format rather than just renaming it. The first one was WNSH in New York. This is also somewhat of a format transfer with 104.1.
