During Super Bowl XLIII in 2009, Comcast's standard-definition transmission of the station was interrupted for approximately 20 seconds replacing KVOA's broadcast of the game with hard-core porn, affecting Comcast's analog subscribers in portions of the Tucson area; it allowed KVOA to join Chicago stations WGN-TV and WTTW and the cable channel HBO (all of which had similar incidents) as victims of broadcast signal intervention. The substitution appears to have been made at Comcast, not at KVOA, leaving KVOA's over-the-air, satellite and other cable providers viewers unaffected. Also, Comcast's high-definition transmission of KVOA was not affected.
