 At times, WOIC's ratings have surpassed WISW's, especially during sporting events, because of the performance of teams on WISW, compared to the performance of teams on WOIC (Clemson Tigers (WOIC) versus Gamecocks).In the 2007 calendar year, teams broadcast on WOIC carried postseason football and basketball coverage; teams broadcast on rival WISW did not, leaving more revenue and higher ratings for these events, which have helped WOIC's ratings against WISW, even though the postseason months are not calculated on Arbitron ratings for the specific days.Until January 25, 2010, WOIC was in a unique position because of the nationally syndicated liberal shows (Air America) that contrasted with the local population.
