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.
NFL International Series Starting in the 2007 season, the National Football League (NFL) has hosted regular season American football games outside the United States every year. Collectively officially known through 2016 as the NFL International Series, from 2017 the series currently has two sub-series, the NFL London Games in London, which has been in place since 2007, and the NFL Mexico Game in Mexico City, which began in 2016 with a predecessor game in 2005.
