WLLI began as WJOL-FM, simulcasting the Beautiful Music of sister-station WJOL-AM in Joliet, Illinois. The call letter switch to WLLI (an anagram for WILL County, Illinois) came in the late 1970s. Music changes over the years included Country, Rock and probably some kind of Contemporary Hit format given the "Listen To Win" sticker above. At one time WLLI was owned by a millionaire who made his fortune from the card game UNO. 96.7 FM is currently a Hot Adult Contemporary outlet "Star 96.7" WSSR.
