[4] In addition to music, WIGY broadcasts Lewiston–Auburn area high school sports.

The station was assigned the WEZR call letters by the Federal Communications Commission on January 18, 2007.

On August 1, 2016, the station began simulcasting on WEZR-FM (92.7, formerly WOXO-FM, whose country music format was transferred to 1450 AM and 96.9 FM), expanding the format's reach to the Oxford Hills area; as a result, the station rebranded to "Maine's Big Z".

[5][6] In April 2019, WEZR rebranded as "Z105.5 & 96.9", reflecting the move of its Oxford Hills simulcast from WEZR-FM to WOXO (now WPNO).

[7] WEZR, along with its sister stations, went off the air March 29, 2020, citing financial considerations that included expected reduction in advertising revenue attributed to COVID-19.
