WAGM-TV history

In 1957, Glidden sold Aroostook Broadcasting to Community Broadcasting System, a company controlled by former Governor Horace Hildreth, who also owned WABI-AM-TV in Bangor.

Soon afterward, the station changed its primary affiliation to NBC, matching WABI-TV; however, WAGM-TV maintained secondary affiliations with CBS and ABC. It returned to being a primary CBS affiliate, again following WABI's lead, in 1959.

Community Broadcasting Service merged with Journal Publications in 1971 to form Diversified Communications.

In 1984, Diversified Communications sold WAGM-TV to NEP Communications, then-owner of WNEP-TV in Scranton, Pennsylvania.

By 1990, WAGM carried the entire CBS prime time lineup, with other network programs airing nightly between 7 and 8.

At one point co-owned by Tom Shelburne, Peter Kozloski, and Norman Johnston, Kozloski assumed full ownership of the station in 1991, retaining the NEPSK name.

When Fox gained broadcasting rights to games from the NFL's National Football Conference in 1994, WAGM aired them since Fox didn't have an affiliate in Presque Isle; this made it the only station in the United States to air programs from all four major networks at the same time.

The station moved its transmitter site in 1999 to the summit of Big Rock ski resort on Mars Hill Mountain's southwestern face.

For the United States digital transition on June 12, 2009, WAGM applied for a 10 kilowatt digital signal and moved its transmitter to the northern section of Mars Hill Mountain.

In April 2015, WAGM was sold to Gray Television for $10.25 million.
