WGBX-TV (channel 44), branded GBH 44, is the secondary PBS member television station in Boston, Massachusetts, United States.

WGBX-TV provided the first gavel-to-gavel telecast of an American state legislature in 1984 when the Massachusetts House of Representatives agreed to have their sessions televised in full, and it was a test bed for experimentation with new digital audio standards in the late 1980s.

[8] On The Most Dangerous Game, telecast in 1967, viewers could call a telephone number to control the movement of a fictional country, Transania, in a hypothetical foreign policy crisis.

[12] The program attracted widespread national and international interest; other public stations copied the format, as did the BBC, which launched Open Door in 1973.

[13] In 1973, as part of an initiative by the WGBH Educational Foundation, it and nine other public stations in northeastern cities began airing an open-captioned version of the ABC Evening News.

[14] WGBX began airing live, gavel-to-gavel coverage of the Massachusetts House of Representatives in 1984, making it the first state legislative chamber to have full, unedited proceedings televised.

[17] Beginning in 1986 and continuing through at least 1988, with special FCC permission, it was the only station in the United States authorized to broadcast pulse-code modulation (PCM) digital audio on its video signal; the audio programs, primarily simulcasts of WGBH-FM aired overnight but also including specially recorded concerts, could then be decoded from the video tape by residents with the appropriate decoder equipment.

[22] In 1999, the tower used by WGBX-TV in Needham, owned by WBZ-TV, was overhauled to support digital broadcasting for its tenants, including WBZ, WGBH and WGBX, and WCVB-TV.

[28] The WGBH Educational Foundation had previously warned that defective equipment might force the station to close prior to the June transition date.
