WKPT was also one of the first stations in the country to utilize a newly adopted (at the time) FCC rule called must-carry that required local cable companies to black out stations in nearby cities affiliated with the same network that were carried on local cable systems and cover the channel with the local network affiliate. As a result, the easily receivable off-air network signal from WLOS, away, was always blacked out on cable systems in the Tri-Cities while being covered by the WKPT signal any time both stations were broadcasting ABC programming. Local WLOS programming was not blacked out. After deregulation of the cable industry, stations from adjacent markets were taken off most local cable systems altogether in favor of satellite stations like TBS, WGN, CNN, and others.
