The overall theme of the Super Bowl entertainment was to celebrate the [[United States Bicentennial]]. Each Cowboys and Steelers player wore a special patch with the Bicentennial logo on their jerseys.

This was the first Super Bowl where somebody other than the game's referee tossed the coin, in this case, [[John Warner]] who was the [[United States Secretary of the Navy]] from 1972 to 1974. Prior to 1976, the coin toss was held a half-hour before kick-off.

The performance event group [[Up with People]] performed during both the pregame festivities and the halftime show titled "200 Years and Just a Baby: A Tribute to America's Bicentennial". Up with People dancers portrayed various American historical figures along with a rendition of [[Steve Goodman]]'s "[[City of New Orleans (song)|City of New Orleans]]".  Singer [[Tom Sullivan (singer)|Tom Sullivan]] sang the national anthem.

Scenes for the 1977 [[thriller film|suspense film]] ''[[Black Sunday (1977 film)|Black Sunday]],'' about a fictional terrorist attack on the Super Bowl via the [[Goodyear Blimp]], were filmed during the game.

This was the last Super Bowl to kick off as early as 2:00&nbsp;p.m. (EST), thereby allowing a finish time before the commencement of many of the nation's evening church services.

This was the first Super Bowl where the play clock was visible to teams and spectators. Visible play clocks were mandated by NFL rules beginning with the [[1976 NFL season|1976 season]].

This was the last Super Bowl where the coin toss was conducted 30 minutes prior to kickoff. Beginning with the next season, the official coin toss was moved to three minutes before kickoff in the center of the field, leaving coaches to scramble to put the proper specialty unit on the field. From 1947 to 1975, a "mock toss" was held three minutes prior to kickoff at midfield to inform fans and media of the result.
