The next three AFL-NFL World Championship Games, later renamed the "Super Bowl", were then divided by the two networks (with each network broadcasting the game exclusively): CBS broadcast Super Bowls II and IV while NBC covered III. When NBC Sports broadcast Super Bowl III, sports broadcasts were produced under the oversight of the NBC News division (this remained the case until 1978, long after both CBS and ABC had spun off their sports operations into departments separate from their news divisions). Curt Gowdy handled the play-by-play duties and was joined by color commentators Al DeRogatis and Kyle Rote in the broadcast booth. Also helping with NBC's coverage were Jim Simpson (reporting from the sidelines) and Pat Summerall (helping conduct player interviews for the pregame show, along with Rote). In an interview later conducted with NFL Films, Gowdy called it the most memorable game he ever called because of its historical significance. While the Orange Bowl was sold out for the game, the live telecast was not shown in Miami due to both leagues' unconditional blackout rules at the time. This game is thought to be the earliest surviving Super Bowl game preserved on videotape in its entirety save for a portion of the Baltimore Colts' fourth-quarter scoring drive.
