Before the switch, Wilmington was the only portion of North Carolina (and one of the few in the Eastern Time Zone) without an over-the-air Fox affiliate of its own. Until this point in time, the area's cable systems piped in the national Foxnet service or WLFL in Raleigh. As a result of WSFX's affiliation switch, Wilmington did not have an over-the-air CBS affiliate until March 2000 when low-powered UPN affiliate WILM-LP switched its primary affiliation to CBS. During that time, cable systems supplemented the area with either WRAL, WNCT, or WBTW.
