The two stations share studios on New Britain Avenue in West Hartford and transmitter facilities on Rattlesnake Mountain in Farmington, Connecticut.

[4] The station has been with NBC since sign-on, though during its first two and a half years, it secondarily carried CBS programming as one of two affiliates in Connecticut,[5] along with WNHC-TV (now WTNH) in New Haven.

[8][9][10] In its first stint as an NBC-owned station, channel 30 failed to gain much headway in the ratings, largely because television manufacturers were not required to include UHF tuning capability until 1964.

[11][12] As part of the deal, Springfield Television, the owner of fellow NBC affiliate WWLP in Springfield, Massachusetts, was to have held a one-third share in channel 30; it abandoned this stake before the deal's completion after concerns arose over WWLP and WNBC's overlapping coverage areas, but continued to hold an option to reacquire it for some time afterward pending FCC approval.

[13] In May 1960, channel 30's callsign changed again – this time to WHNB-TV (for Hartford-New Britain); NBC reclaimed the WNBC calls for its flagship radio and television combination (the former WRCA-AM-FM-TV) in New York City.

[14][15] In 1966, WHNB-TV became, once again, one of two NBC affiliates in Connecticut; the network signed with Waterbury-licensed WATR-TV (channel 20) to get its programming into New Haven on a strong signal.

[19] Shortly after assuming control in the spring of 1978, channel 30's call letters were changed to the present WVIT on June 12 (for "Viacom International Television") to reflect its new ownership.

In 1993, WVIT and WTXX entered into a part-time local marketing agreement after talks with Fox affiliate WTIC-TV (channel 61) failed.

[28] WVIT, the first television outlet Viacom purchased was the last station to be sold, as Viacom agreed to trade channel 30 to former owner NBC in return for future purchase rights to WWHO in Chillicothe, Ohio, and WLWC in New Bedford, Massachusetts, two UPN-affiliated stations NBC was operating by way of local marketing agreements.

[31] ZGS had sold WRDM's spectrum in the FCC's incentive auction for $10,574,516 and indicated that the station would enter into a post-auction channel sharing agreement, which occurred with WVIT at the start of the year.

[33] On June 16, 2017, WVIT announced that it would not air that week's edition of Sunday Night with Megyn Kelly, which featured an interview with radio host Alex Jones.

The station cited viewer, advertiser and management sensitivities to the views of Jones, as he had previously expressed a denial of the Sandy Hook Elementary School shootings.
