WTVX (channel 34) is a television station licensed to Fort Pierce, Florida, United States, serving the West Palm Beach area as an affiliate of The CW. It is owned by Sinclair Broadcast Group alongside CBS affiliate WPEC (channel 12) and two low-power, Class A stations: MyNetworkTV affiliate WTCN-CD (channel 43) and Roar owned-and-operated station WWHB-CD (channel 48). The stations share studios on Fairfield Drive in Mangonia Park; WTVX's transmitter is located southwest of Palm City, Florida.

WTVX was established in Fort Pierce in 1966 and was the third—and successful—attempt to sustain a television station in that city. It was the CBS affiliate for areas north of Palm Beach County. In 1980, a new transmitter facility and substantial power increase added the Palm Beaches to its coverage area. A decade later, a network affiliation shuffle in the West Palm Beach market led to WTVX losing its CBS affiliation. After being spurned by ABC, WTVX became an independent station and shut down its news department. The station was sold to Krypton Broadcasting, which soon after struggled through a lengthy bankruptcy case that ended with WTVX being auctioned off. An affiliate of UPN from 1995 to 2006 and The CW since, the station has made several further and short-lived attempts at local news programming.

Fort Pierce had previously had a television station, WTVI (channel 19), in two separate stints from 1960 to 1962. It had been a money-loser and had failed twice for financial reasons. However, one of the minority owners of WTVI thought the venture was worth trying again in the wake of the All-Channel Receiver Act mandating UHF tuning in television sets. In April 1965, Indian River Television, a company owned by J. Patrick Beacom (mayor of St. Lucie Village) and Bill Minshall, filed to build a new television station on channel 19 in Fort Pierce, which the Federal Communications Commission (FCC) granted on July 28 of that year. The application had been amended to specify channel 34 when the FCC overhauled UHF allotments nationwide that summer.

Indian River then spent $50,000 to acquire the studio and transmitter site along US 1 just south of the St. Lucie–Indian River county line, built for WTVI in 1960, from that station's founder, Gene Dyer. Indian River reinstalled equipment after the structure had been stripped several years prior.

WTVX went on the air on April 5, 1966, after broadcasting a test pattern since March 24. It immediately affiliated with CBS; previously, cable companies had imported Miami CBS affiliate WTVJ (channel 4). However, WTVX could not air every CBS show immediately because some sponsors withheld their programs from the new station. The new station's 26 kW of effective radiated power did not reach past Martin County. Due to WTVX's weak signal, WTVJ continued to claim the Palm Beaches as part of its primary coverage area; when that station opened a news bureau in West Palm Beach in 1970, 12.4 percent of its audience was said to come from Palm Beach County.

After a sale announcement in 1970 was later labeled "premature", the Minshall and Koblegard families—which by this point owned the entirety of the station—reached a deal in 1977 to sell WTVX to Frank Spain, owner of WTWV in Tupelo, Mississippi. However, a federal investigation into station practices was sparked when Edward Trent, an employee who had been fired the previous year, told the FCC that WTVX engaged in an illegal practice known as "clipping", replacing commercials and short credits sequences from network programs with local commercials. The commission proceeded to designate the renewal of WTVX's broadcast license for hearing on the matter. WTVX admitted to carrying out clipping in June 1978, claiming it had done so because it had oversold ad time; the station ultimately had its license renewed and paid a $10,000 fine. That allowed the sale of WTVX to Frank Spain to proceed.

Spain launched a major capital campaign to improve the station's facilities. More than $5 million was put into WTVX, including newer and larger Fort Pierce studios on North 25th Street (SR 615) and the commissioning of a 1,549-foot (472 m) tower after some early county opposition. It featured the most powerful UHF transmitter in Florida, operating at the UHF maximum of 5 million watts. The station finally had a signal capable of reaching the Palm Beaches, filling what had been something of a donut hole in CBS coverage. In addition, the more powerful WTVX began appearing on Palm Beach County cable systems that had not previously carried it, further extending its reach.

It's [declining attendance] a disturbing trend, but one that can be reversed. We can reverse it by winning, getting into the Super Bowl, getting a new stadium and getting television stations like that one in Fort Pierce off our backs.
