WZVN-TV (channel 26, cable channel 7), branded as Gulf Coast ABC, is a television station licensed to Naples, Florida, United States, serving as the ABC network affiliate for Southwest Florida. It is owned by Montclair Communications, which maintains a local marketing agreement (LMA) with Hearst Television, owner of Fort Myers–licensed NBC affiliate WBBH-TV (channel 20), for the provision of certain services. The two stations share studio facilities on Central Avenue in Fort Myers; WZVN-TV's transmitter is located along SR 31 in unincorporated southeastern Charlotte County.

Channel 26 went on the air in Naples on August 21, 1974, as WEVU, the first ABC affiliate in Southwest Florida. It operated from studios in Naples and suffered from turnover in ownership as well as poor local ratings. This continued even though the station moved its transmitter further north from its original location in the late 1980s in order to improve its signal in Fort Myers. In 1994, then-owner Ellis Communications entered into an LMA with then-WBBH owner Waterman Broadcasting by which WBBH began to provide the station's news programming. The station itself was then sold in 1996 to Montclair Communications, whose principal has family and business ties with the Waterman family. Though news ratings have remained low, the Waterman LMA gave the station access to additional resources and a path to profitability. The two stations have separate newscasts with separate anchors, though they share reporters, news resources, and—as of 2025—a common news brand.

In May 1972, the Federal Communications Commission (FCC) approved the addition of television channel 26 to Naples at the request of the Gulfshore Television Corporation. Three months prior, G. Vernon Lundquist, founder of Gulfshore, had resigned from his job at WINK-TV in Fort Myers after 20 years and petitioned for the addition of the channel in Naples. Gulfshore then applied for the channel, as did Gray Communications Systems of Albany, Georgia. The construction permit was granted to Gulfshore in July 1973, and the company immediately began to pursue affiliation with ABC. Construction then began on studios located off US 41 in Bonita Springs; a change in the antenna site pushed back completion of the facility.

WEVU first signed on the air on August 21, 1974. Its early months quickly turned turbulent. In December 1974, Lundquist was asked to take a leave of absence by the board of directors; his wife Marilyn, who was tapped to be the operations manager, was fired. Early the next month, Gulfshore's minority stockholders sued Lundquist, saying that the stock he held was illegally issued; at that same time, the station fired 15 staff, canceled its early evening news, and began signing on at 11:30 a.m. instead of 7 a.m. In a summary judgment that March, a circuit court found in favor of the other stockholders.

In a second lawsuit filed in May 1975, more details surfaced about Lundquist's tenure running the new station. According to the suit filed by Gulfshore's other stockholders, Lundquist solicited a WEVU employee to appear in a sex movie; failed to pay the lease on the station's broadcast equipment; used his own company to make commercials, competing with WEVU's own advertising department; and hired relatives who were unqualified for their positions, jeopardizing the station's future. In addition, the minority owners of Gulfshore said that, by failing to obtain a direct link with ABC, the station had lost $200,000 in advertising business; WEVU obtained its ABC programming off-air from Sarasota's WXLT (channel 40, now WWSB), leaving it at the mercy of WXLT's own preemptions of ABC network fare.

In May 1976, Lundquist sold his controlling interest in WEVU to the other seven stockholders, after his shares were reinstated by an appeals court. With the other members of Gulfshore in control, the company set out to try and get WEVU on the right foot after the station nearly closed; they hired Joe Buerry, one of the founders of WBBH-TV, as the new general manager, and WEVU also restored the local news it had cut back earlier. In one embarrassing mishap, in May 1978, a film distributor mixup was responsible for the station airing 30 minutes of an X-rated film instead of its intended late feature, Daring Game.

In May 1978, Gulfshore announced the sale of channel 26 to Caloosa Television, a subsidiary of the Home News Company of New Brunswick, New Jersey, for a total of $3.3 million. WEVU was the seventh broadcasting property owned by Home News and second TV station.

For years, it had been a standing complaint of viewers, and southwest Florida's TV stations, that Miami Dolphins games that did not sell out could not be aired in the Fort Myers–Naples market. In 1979, then-new news director Jack Speiss was surprised when the station did not air a Monday Night Football game because of a blackout; he eventually was able to telephone then-Dolphins owner Joe Robbie, who told him in no uncertain terms, "I'm not going to allow you to broadcast it." Tension over what came to be known locally as the "Robbie Rule" boiled over in 1984 when the Dolphins blacked out WEVU again on Monday night. However, once WEVU's scheduled movie ended, and with the game still going on, channel 26 joined the network telecast in progress, and the general manager issued a statement criticizing the "Robbie Rule" which was read on the station's late newscast.
