Construction and early years When the
Federal Communications Commission (FCC) resumed granting new TV station applications in 1952 after a multi-year freeze, it allocated
Portland, Maine, two
VHF channels, 6 and 13. The freeze had affected the first television station application in Maine, made by
Guy Gannett Broadcasting Services, owners of radio stations
WGAN in Portland and
WGUY in
Bangor. In May 1952, Guy Gannett announced its intention to apply for channel 13. Later in 1952, the Community Broadcasting Service, owner of Bangor radio station
WABI, applied for channel 13 in Portland. With competing applications, channel 13 was pushed into a
comparative hearing situation, and the FCC in October 1952 ordered hearings be held on the two applications apiece it had received for channels 6 and 13. A third channel played into the channel 13 hearing dispute. Channel 8 had been allocated for use at
Mount Washington, New Hampshire, from which it would cover Portland, and Mount Washington TV, Inc., was seeking that channel. Mount Washington and Community had a stakeholder in common:
Horace Hildreth. In May 1953, Guy Gannett called on Hildreth to select one or the other application to prosecute because he could not own both channels, with their overlapping coverage areas. On July 8, 1953, Mount Washington TV won the construction permit for channel 8, on the condition that its stockholders remove themselves from competing applications in Portland; these included not only Hildreth but the owners of an applicant for channel 6. If they did so, each channel would have one contested applicant. Another stockholder in Community, Murray Carpenter, declared he had no intention to drop out of the channel 13 contest. Carpenter responded to the FCC action by selling out his ownership interest in WABI radio and
WABI-TV to Hildreth in exchange for his shares in the channel 13 applicant. He then filed for channel 13 under his own name in August. On November 2, days before hearings were to begin, Carpenter simultaneously withdrew his channel 13 application and agreed to buy WGUY radio from Guy Gannett. He told the FCC that he had been unable to find financial backing for the TV station. This left Guy Gannett unopposed for channel 13; the firm received a construction permit on November 19 and declared its intention to be on the air within six months. The WGAN-FM site at Blackstrap in
Falmouth was renovated to house the channel 13 transmitter facility; it had been built in 1946 with a possible television use in mind. WGAN-TV began broadcasting on May 16, 1954, as a primary affiliate of
CBS with additional programming from
ABC. It was the fifth TV station on the air in Maine; it displaced the combination of
WPMT (channel 53) and WLAM-TV (channel 17), a pair of UHF stations in Portland and
Lewiston–
Auburn, as the local outlet for CBS and ABC programs. At the outset, WGAN-TV offered a variety of local programs. Three newscasts a day were scheduled, utilizing the resources of Guy Gannett's five Maine newspapers; it also aired a daily afternoon variety show,
The Lloyd Knight Show, and locally produced educational and nature programs. The station broadcast from an incomplete tower on reduced power until June 30. Channel 8 from Mount Washington debuted in September as
WMTW. It had affiliations with CBS, ABC, and
DuMont Television Network, splitting much of channel 13's audience for network programming. WMTW continued to air some CBS programs until July 1958, when it became an all-ABC station. In addition to its main studio at 390 Congress, WGAN-TV maintained a "sidewalk studio" at street level at High and Congress streets. WGAN announced its intention to build a new, taller TV tower in 1958. Such an expansion had been contemplated from the start, but an attempt to shuffle VHF television station allocations in New England—and possibly force WGAN-TV to another channel—stalled the move. A mast was erected on Brown Hill near
Raymond and began use on October 30, 1959. It was the world's tallest man-made structure at its completion, though the next year
KFVS-TV in
Cape Girardeau, Missouri, eclipsed it with a tower. While WGAN-TV was still losing money by 1961, the station improved its financial standing by the middle of the decade and attracted more than 40 percent of TV advertising revenue. In February 1967,
WGAN-FM 102.9 began broadcasting from the Raymond tower. Operations of WGAN AM and WGAN-TV moved in 1977 from downtown Portland to space in part of a former
W. T. Grant department store in Portland's Northport Plaza shopping center. When the radio stations were sold to Taylor Communications of Maine during 1983, the WGAN
call letters remained with them; WGAN-TV became WGME-TV, "We're Gannett of Maine", on January 1, 1984. Channel 13 had been the traditional news leader in the Portland market until the mid-1980s. In February 1986, WCSH surpassed WGME at 11 p.m. and tied channel 13 in the vital 6 p.m. news slot. Later that year, WCSH would surpass WGME at 6 and proceed to do so for at least the next 16 years. In 1989, WGME debuted a 5:30 p.m. newscast,
1st News. It was the first time a Portland station had produced an hour of early evening news since WCSH tried the idea in the 1970s. Further news expansions came in 1993 with the debut of
Daybreak, a morning newscast, and in 1997 with a 5 p.m. news half-hour. The latter helped give WGME the edge over WCSH in the 5:30 p.m. half-hour where the two stations competed.
Sinclair ownership Motivated by the impending expiration of the family trust that owned the company and a seller's market for broadcasting properties, Guy Gannett Communications put itself up for sale in 1998, ending 110 years of its history as a publisher.
The Seattle Times Company acquired Guy Gannett's newspapers, while the firm's television stations were purchased by
Baltimore-based
Sinclair Broadcast Group for $310 million. WGME-TV had been the last major station in Portland to be locally owned. The Guy Gannett purchase gave Sinclair diversification into affiliates of the
Big Three networks and beyond a portfolio heavy with Fox,
WB, and
UPN stations. The transaction closed on April 30, 1999. One of the first moves made under Sinclair was the cancellation of weekend morning and noon newscasts in order to focus resources on weekday news programs with more viewers. By 2011, WGME was still in second place to WCSH in the evening news ratings, especially at 6 p.m., where channel 6 had more than twice as many viewers. On February 5, 2007, WGME-TV began producing a nightly 10 p.m. newscast for
WPFO (channel 23), then Portland's
Fox affiliate, after a news share agreement was established between the two. It aired from a secondary set at WGME's studios. The news relationship expanded in 2010 when the newscast was lengthened to an hour; a new two-hour morning newscast from 7 to 9 a.m., titled
Good Day Maine, was added. In October 2013, Sinclair acquired the non-license assets of WPFO from Corporate Media Consultants Group for $13.6 million. An affiliate of Sinclair,
Cunningham Broadcasting Corporation, filed to acquire the license assets for $3.4 million on November 19, but the deal was not approved until June 23, 2017. In 2024, WGME began airing a new lifestyle program,
ARC Maine, at 9 a.m.; the WPFO morning newscast was shortened to an hour, with the 8 a.m. hour replaced by
The National Desk. Sinclair filed to buy WPFO outright from Cunningham in August 2025, following a decision by the
United States Court of Appeals for the Eighth Circuit that struck down limitations on ownership of two of the four highest-rated TV stations in a market. On December 8, 2025, the Fox affiliation was moved to WGME-TV's second subchannel, while WPFO's main channel flipped to
Roar. , WGME–CBS airs hours a week of local news programs, not including news on WGME–Fox. In addition to WGME, Sinclair owns Dielectric, a manufacturer of antennas located in Raymond that it purchased in 2013. ==Notable former on-air staff==
