Private microwave relays of network programming were prevalent for many medium- and small-market stations before the advent of AT&T commercial microwave. WHIS-TV (now WVVA) in Bluefield, West Virginia operated its own private microwave relay that brought NBC to Bluefield from WSLS-TV in Roanoke, Virginia. In its early days, WSMV-TV in Nashville received its NBC feed from WAVE-TV in Louisville; and WSAZ-TV in Huntington, West Virginia operated a private microwave to deliver NBC first from WLWT in Cincinnati, then from WLWC (now WCMH-TV) in Columbus, Ohio.
