WISW (1320 AM) was a radio station licensed to Columbia, South Carolina. The Cumulus Media outlet was licensed by the Federal Communications Commission (FCC) to broadcast with 5,000 watts daytime and 2,500 watts nighttime, directional. Until going silent in March 2025, WISW was a sports radio station that went by the name ESPN Radio 1320.
WISW was formerly known as "News Talk 1320 WIS" or "WIS Radio", taking the base of its call sign from the former WIS. The latter station was the longtime sister station of WIS-TV, Columbia's long-dominant NBC affiliate. The WIS portion of the call letters stood for "Wonderful Iodine State". The former WIS is now WVOC 560 & 103.5.
Cumulus Media also owned WTCB 106.7, WOMG 98.5, WNKT 107.5, and WLXC 103.1 in the Columbia radio market. All 5 stations shared studios located at the Granby Building in Cayce; the WISW transmitter was in West Columbia. The station operated from 1945 to 2025.
