In 1975, the council changed its name to the National Football League (NFL), and embarked on an ambitious plan by establishing the NFL Night Series in 1976. The Night Series was a new competition, played concurrently with the premiership seasons, among twelve clubs from the VFL, SANFL and WANFL invited based on their finishing positions from the previous year. The event was mostly played on Tuesday nights, with night games at Norwood Oval in Adelaide, which was the premier night football venue in the country at the time. The event was the first fully national club competition in Australian rules football; and, as all games were televised live in colour on Channel 9, the event opened unprecedented revenue streams from television rights and sponsorship opportunities for the sport.
