Ed Sabol founded NFL Films. He originally established it as Blair Motion Pictures after winning the rights to film the 1962 NFL championship game for $5,000. The NFL's owners bought the company in 1965 and renamed it NFL Films.
NFL Films is based in Mount Laurel, New Jersey, in the Bishop's Gate industrial park. The facility includes an in-house 16mm and 35mm color negative processing lab and a vault holding over 100 continuous years of football footage.
NFL Films has won 112 Sports Emmys.
NFL Films is known for using film rather than video, dedicating one camera to slow-motion shots, placing microphones on the sidelines, dubbing in local radio calls over key plays, and using muscular orchestral scores. The tight-on-the-spiral slow-motion shot of a spinning football in flight is one of its most recognizable techniques.
NFL Films cameras attended every game during an era when many sports telecasts were either not recorded or had their tapes destroyed and recycled. That practice did not fully stop until 1978. Without NFL Films, no surviving footage of the early Super Bowls would exist.
Composer Sam Spence alleged that NFL Films persuaded him to sign a contract surrendering all rights to his music under the claim that it would protect his work from theft. Spence alleged NFL Films then used that contract to retain ownership of his compositions outright.
