KJOZ started out as a full service country and western station using the call sign KMCO (standing for Montgomery County) in 1951, owned by Reagan Smith & Fred Perry Sr.
After several months IDing as simply "880 KJOJ" with Siddiqui's programming, it returned to simulcasting Houston's 1230 KQUE as Regional Mexican "Radio Ranchito" then as "La Ranchera".
During the license reassignment process, Daij Media filed to change the call sign to KJOZ upon consummation of the sale, in order to disassociate the station from the FM counterpart located in Freeport, Texas.
On April 13, 2015, KJOZ dropped Spanish Christian programming and relaunched as an urban talk station with the slogan "Where diversity finds its voice."
On April 8, 2016, Urban Talk & Oldies was dropped from 880 KJOZ, returning to the previous Spanish Christian programming of owner Radio Aleluya.
