• October 1 (10:00 a.m. local time; September 30 in the Americas) – Home Box Office cable television becomes the first pay-per-view television network to deliver a continuous signal via satellite by broadcasting the "Thrilla in Manila" boxing title fight (in which Muhammad Ali defeats Joe Frazier in Manila, Philippines) live to the United States.^[1] The fight is watched live by well over 100 million and perhaps as many as one billion viewers worldwide^[2] including the 500,000 on HBO^[3] and 100 million viewers watching on closed-circuit theatre television.^[4] It is broadcast in the Philippines by KBS and in the United Kingdom by the BBC
• October 11 – The premiere episode of Saturday Night Live is broadcast on NBC

• October 21 – NBC broadcasts the now legendary 12-inning long sixth game of the World Series between the Boston Red Sox and Cincinnati Reds. The game ends with Boston catcher Carlton Fisk's home run to send the series to a climatic seventh game. In what becomes an iconic baseball film highlight, the NBC left-field game camera^[5] catches Fisk wildly waving his arms to his right after hitting the ball and watching its path while drifting down the first base line, as if he is trying to coax the ball to "stay fair". The ball indeed stays fair and the Red Sox tie the Series. (According to the NBC cameraman Lou Gerard, located inside the left field wall scoreboard, cameramen at this time are instructed to follow the flight of the ball. Instead, Gerard is distracted by a rat nearby, thus he loses track of the baseball and instead decides to capture the image of Fisk "magically" waving the ball fair).^[6] The game is ranked Number 1 in MLB Network's 20 Greatest Games.^[7]
