what is considered the modern era of the nfl
History of the National Football League In the 1970s and 1980s, the NFL solidified its dominance as America's top spectator sport,[citation needed] and its important role in American culture. The Super Bowl became an unofficial national holiday and the top-rated TV program most years. Monday Night Football, which first aired in 1970, brought in high ratings by mixing sports and entertainment. Rule changes in the late 1970s ensured a fast-paced game with lots of passing to attract the casual fan.
