Prime Sports Upper Midwest was an American regional sports network owned by Hubbard Broadcasting and Liberty Media, which operated as an affiliate of the Prime Network.
The network struggled only having one team's sports rights against the more established Midwest Sports Channel, which had the rights to Minnesota Twins baseball, and the backing of Midwest Radio and Television, the owners of the dominant WCCO stations.
MSC's strength in the Twin Cities became more dominant in 1992 after CBS Corporation purchased Midwest Radio and Television, along with the Twins' win in the 1991 World Series, while PSUM was stunted by the terminal mediocrity of the Timberwolves in the 90s, along with other challenges to Hubbard's longevity in the Twin Cities market, namely Gannett NBC affiliate KARE permanently unseating Hubbard's KSTP-TV as the market's spirited competitor to WCCO, and KMSP-TV beginning its slow rise in viewership and news and sports strength.
In the spring of 1995, MSC signed an agreement with the Timberwolves to acquire the exclusive regional cable television rights to the team's games beginning with the 1995–96 season.
As a result, on October 5, 1995, Hubbard and Liberty Media announced that Prime Sports Upper Midwest would be shut down.
