The National Educational Association set up an educational television project in Guam in August 1967, in line with similar plans in other US overseas territories, under the perception that television would bring the "modernization of education". Such consultancy would culminate in the creation of KGTF, with the launch set for 1970. The station signed on the air on October 30, 1970, with only hours of programming Monday through Friday, of which they would later expand throughout its 50-year history, including producing local shows and various projects. Original materials from PBS Guam have been contributed to the
American Archive of Public Broadcasting. The channel was made possible by a $150,000 grant by the Department of Health, Education and Welfare. That year, it became a PBS branch station by the authorization of the 12th Guam Legislature Bill, creating the Guam Educational Telecommunications Corporation. KGTF shut down its analog signal, over VHF channel 12, on January 23, 2009, approximately five months before the official date on which full-power television stations in the United States
transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition
VHF channel 5, using
virtual channel 12. KGTF is a partner of the
Pacific Community's television newsmagazine
The Pacific Way. PBS Guam received PBS' overhaul branding in late-November 2019. ==Subchannels==
