Short answers, pulled from the story.
Pete Rozelle was the commissioner of the National Football League from January 1960 until November 1989. During his tenure he oversaw the AFL-NFL merger, the creation of the Super Bowl, the launch of Monday Night Football, the expansion of the league from 12 to 28 teams, and the negotiation of large national television contracts that transformed the NFL into one of the most successful sports leagues in the world.
Rozelle was 33 years old when he was chosen as NFL commissioner at a the 26th of January 1960, meeting, making him the youngest commissioner in NFL history. The owners took 23 ballots before settling on him.
Monday Night Football premiered in September 1970 after Rozelle proposed the prime-time weeknight concept to Roone Arledge, then president of ABC Sports. The first game featured the Cleveland Browns against the New York Jets, with the Browns winning 31-21, and the first announcing team consisted of Don Meredith, Howard Cosell, and Keith Jackson.
The Rozelle Rule, enacted in 1963, required any team that signed a free agent to compensate that player's former club with players and draft picks, with Rozelle as the sole arbiter of the compensation. On the 30th of December 1975, Judge Earl R. Larson declared the rule a violation of antitrust laws in Mackey v. National Football League.
Yes. After President Kennedy was assassinated on the 22nd of November 1963, Rozelle consulted with White House press secretary Pierre Salinger, his former classmate at the University of San Francisco, who urged him to proceed. Rozelle allowed the games to go ahead, though he later said it might have been wiser to cancel them. The AFL and most major colleges did not play that weekend.
Rozelle was inducted into the Pro Football Hall of Fame in 1985, while he was still serving as NFL commissioner. The annual Pete Rozelle Radio-Television Award, recognizing contributions to broadcasting in professional football, was established in 1989 upon his retirement.
