KVZK-TV broadcasts from the National Register-listed Michael J. Kirwan Educational Television Center in Utulei and maintains a tower on Mount Alava.

[3] KVZK-TV operates a series of television channels that provide local interest and United States network programming.

[13] Much of this investment was secured by Lee's connection to congressman Michael J. Kirwan, who had long taken an interest in American development efforts in the Pacific.

Lee's replacement, Owen Aspinall, and the National Association of Educational Broadcasters had a falling out, hurting the recruitment of mainland teachers into the program.

[21]: 160  As a result, in 1975, KVZK-TV was separated from the Department of Education into its own agency, the Office of Television Operations; station staff were not consulted about the change.

In 1974, it sent its first employees to mainland broadcasting schools;[14]: 87  at the same time, Samoans were sent to WLUK-TV in Green Bay, Wisconsin, to train on color camera equipment.

[25] Jon A. Anderson, who left in 1977 to take a job with Pacific Telestations on Guam, described the station's output that year as "a combination of American commercial and public television programming equal to that available in most communities in the United States".

[24] In 1980, American Samoa voters could watch their ballots be counted live at the studios, one at a time;[27] by that same year, however, television's role had been vastly reduced, and many classroom sets were inoperable.

[21] Plans were also considered in 1976 to gift one of the surplus high-band VHF transmitters—not capable of color[28]—to Samoa to start what would be the first television station there.

[30] After having aired on KKHJ-LP from 2005 to 2012, NBC returned to KVZK in 2014, utilizing a direct feed of KHNL-TV provided by the American Samoa Telecommunications Authority (ASTCA).

[31] Simultaneous with the return of NBC, the 30-minute newscast, Talafou, was extended to an hour, allowing for half-hour segments in Samoan and English.

[35] In 2019, for just the second time in its history, KVZK-TV presented live programming from Samoa when it carried daily coverage of the 2019 Pacific Games.
