National Telefilm Associates, which later purchased WNTA-TV in the New York City area, purchased the 75 percent of United Television not owned by MGM for 0,000 in November 1957, joining it to the NTA Film Network until it ended in 1961.
The KMSP call letters were featured on prop television cameras in the May 29, 1963 episode of the CBS sitcom The Many Loves of Dobie Gillis, produced by 20th Century Fox Television; the show was loosely set in the Twin Cities area.
Throughout its years with ABC, KMSP was notorious for having a sub-standard news department with large staff turnover.
Ratings were dismal with KMSP obtaining only one-third of the viewing audience of each of their two competitors, CBS affiliate WCCO-TV and NBC affiliate KSTP-TV.
The station grew out of an AM station, KEYD (1440 AM, now KYCR), with which it was co-owned until mid-1956.
When the Federal Communications Commission (FCC) opened up bidding for the channel 9 construction permit, WLOL and WDGY (now KTLK) also expressed interest.
The station is also carried in Canada on Shaw Cable's Thunder Bay, Ontario system and on Manitoba Telecom Services (MTS) in the province of Manitoba.
Although it now faced having to buy an additional 19 hours of programming per day, it also would not have to invest nearly as much into its news department.
