Eliteserien was founded in 1937 as Norgesserien (English: "The League of Norway"), and the first season was the 1937–38 season. The structure and name of Eliteserien, along with Norway's other football leagues, has undergone frequent changes. The top level was renamed "Hovedserien" in 1948, "1. divisjon" (now used by the second level league in Norway) in 1963, then "Tippeligaen" (named for the main sponsor) in 1990. Starting with the 2017 season the league adopted the current "Eliteserien", after NFF decided to totally drop any sponsor's names from the name of the league. The broadcasting rights were in December 2015 secured by Discovery Networks who signed a six-year deal giving them rights to broadcast all the 240 games in Eliteserien from 2017 to 2023. The deal was worth NOK 2.4 billion. The league generates NOK 400 million per year in domestic television rights.
