The corporation has broadcast outlets scattered across Minnesota, Wisconsin, New York, and New Mexico, though the flagships are the KSTP radio — KSTP (AM), KSTP-FM — and television — KSTP-TV — stations serving the Twin Cities region of Minnesota and western Wisconsin.
In 1928, WAMD merged with KFOY radio (first broadcast: March 12, 1924) in St. Paul to become KSTP, which was advertised as being operated by the National Battery Broadcasting Co. Ten years later, in 1938, Hubbard bought the first television camera available from RCA. Following the television blackout brought on by World War II, KSTP started television broadcasts in 1948.
KSTP is still Hubbard's flagship, although there are now three different stations that carry that name. KSTP-TV is affiliated with ABC. KSTP-AM broadcasts a talk radio format, and KSTP-FM broadcasts adult contemporary music.
After the Federal Communications Commission relaxed rules about television station ownership, Hubbard bought a second television station in the Twin Cities. Originally affiliated with the Home Shopping Network when it started operations in 1994, KVBM channel 45 was bought by Hubbard and began broadcasting as KSTC in 2000. The station is normally independent (not affiliated with any broadcast network), but it has been used by KSTP to broadcast ABC network programming when channel 5 is broadcasting coverage of Viking football games or other special shows, including severe-weather coverage.
Aside from terrestrial broadcast stations, other current ventures include the film network ReelzChannel (launched in 2006), arts network Ovation TV, and the Hubbard Radio Network, which is used to distribute KSTP-AM's local talk shows to subscribing radio stations in Minnesota and Wisconsin. The cable channels are run through subsidiary company Hubbard Media Group.
In 1981, Hubbard Broadcasting started U.S. Satellite Broadcasting (USSB), and later was instrumental in the development and launching of the first digital satellite system for television in 1994. The new satellite could deliver 175 channels to a (at the time) tiny, 18 inch dish. USSB's development partner, Hughes Electronics (a General Motors subsidiary), launched their own subscription satellite service called DirecTV. The two services did not compete against each other (they carried different channels), and were often marketed together to subscribers by retailers and in advertisements until DirecTV's 1998 acquisition of USSB.
Hubbard Broadcasting also operated a 24 Hour News station titled All News Channel which featured longtime KSTP anchor Stan Turner. The news channel lasted from 1991 until it folded in 2004.
As of October 2007, engaged in a fevered battle with NABET union repping employees of WNYT Albany.
