WWWZ signed on the air May 10, 1974 as a Brothers Broadcasting-owned, low-power, freeform format station. The station broadcast from a mobile home studio off Hwy 61 near Summerville, SC and was referred to as "3WZ". In 1981, WWWZ switched to its current Urban format as "Z93".
In summer 1999, Z93 added new hosts to "The All-New Breakfuss Club," but this still did not keep the station from finishing second in the morning to WAVF's Howard Stern. Z93 had reached number one on several occasions but usually lost to WEZL. WWWZ was number one with 25-54 listeners in Fall 1999. In Winter 2002, Z93 was number one overall and Tessa and Baby J stayed at number one in the morning with the 25-54 audience. In Spring 2002, Tessa and Baby J were number one with 18-34 listeners.
