The station was assigned the WEZR call letters by the Federal Communications Commission on January 18, 2007.[2] On March 31, 2014, WEZR began simulcasting on 105.5 FM, via translator W288CW, and rebranded as Z105.5. 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.[8] The stations had been up for sale following the death of owner Dick Gleason in February 2019.[9] A sale of the Gleason Media Group stations to Bennett Radio Group was announced in May 2020.[10]
Bennett Radio Group's purchase, at a price of $300,000, was consummated on August 5, 2020. On August 19, 2020, WEZR and WPNO returned to the air as they relaunched the hot AC format as "WIGY", while adding a simulcast on the former WTME (now WEZR).[11] The call sign for 1240 AM was changed to WIGY on September 7, 2020.[2]
