In January, 2013, KBBM changed their format from modern rock to sports and was now branded as "Sports Radio 100.1 The Fan".
On October 5th 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. On the 7th, The Fan moved to 104.1 as 100.1 began stunting with Christmas music as "Santa 100.1". At 10:01 am on the 8th, the station flipped to country, branded as "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 new format rather than just renaming the station, the first being WNSH in New York. This can also be considered a format switch with 104.1.
