KTBC (channel 7) is a television station in Austin, Texas, United States, serving as the market's Fox network outlet. It is owned and operated by the network's Fox Television Stations division, and maintains studios on East 10th Street near the Texas State Capitol in downtown Austin; its transmitter is based at the West Austin Antenna Farm on Mount Larson.

KTBC-TV aired its first television broadcast on Thursday, November 27, 1952, becoming the first television station in Austin and Central Texas. Originally housed in a small studio in the Driskill Hotel, the station was originally owned by the Texas Broadcasting Company (from whom the call letters are taken), which was in turn owned by then-Senator and future U.S. President Lyndon B. Johnson and his wife Lady Bird, alongside KTBC radio (590 AM and 93.7 FM). Lady Bird Johnson used the money from her family inheritance to purchase KTBC-TV, and she remained active with her radio station until she was in her eighties, which led her to become the first president's wife to have become a millionaire on her own. It carried all four major networks at the time: ABC, CBS, NBC and the now-defunct DuMont Television Network. However, it was a primary CBS affiliate. In its early history, it carried roughly 65% of CBS's schedule; NBC and ABC roughly split the remaining coverage in half.

In 1960, the staff of channel 7 produced a film for the Texas Department of Public Safety, entitled Target Austin. The 20-minute film presents the scenario of a nuclear missile strike on the outskirts of Austin and follows the storylines of several characters from the CONELRAD broadcast to the announcement that it is safe to emerge from shelter. The film takes place in Austin, highlighting several iconic locations in the city, and featured an Austin-based cast and crew: including director Gordon Wilkison (of KTBC), narrator Cactus Pryor (also of KTBC), actress Coleen Hardin, and El Rancho restaurant owner Matt Martinez.

KTBC-TV benefited from a quirk in the Federal Communications Commission (FCC)'s plan for allocating stations. In the early days of broadcast television, there were twelve VHF channels available and 69 UHF channels (later reduced to 55 in 1983). The VHF bands were more desirable because they carried longer distances. Since there were only twelve VHF channels available, there were limitations as to how closely the stations could be spaced.

After the FCC's Sixth Report and Order ended the license freeze and opened the UHF band in 1952, it devised a plan for allocating VHF licenses. Under this plan, almost all of the country would be able to receive two commercial VHF channels plus one noncommercial channel. Most of the rest of the country ("1/2") would be able to receive a third VHF channel. Other areas would be designated as "UHF islands" since they were too close to larger cities for VHF service. The "2" networks became CBS and NBC, "+1" represented non-commercial educational stations, and "1/2" became ABC (which was the weakest network usually winding up with the UHF allocation where no VHF was available).

However, Austin is sandwiched between San Antonio (channels 4, 5, 9, and 12) to the south, Houston (channels 2, 8, 11, and 13) to the east, Waco–Temple–Bryan (channels 3, 6, and 10) to the north, and San Angelo (channels 3 and 8) to the west. This created a large doughnut in central Texas where there could be only one VHF license, which became KTBC-TV. Additionally, UHF signals usually do not travel very far over long distances or over rugged terrain. Even though Austin was large enough on paper to support three full network affiliates as early as the 1950s, the technical limitations made several potential owners skittish about the prospects for UHF in a market that stretched from Mason in the west to La Grange in the east, and also included much of the Hill Country. (Of note, while KTBC was the only full-market VHF outlet in Austin, one of the San Antonio-based VHF outlets, PBS member station KLRN also served Austin in the 1960s and 1970s with a signal that covered both markets midway from a transmitter near New Braunfels until 1979 when the station started to focus on San Antonio exclusively and KLRU was launched to serve Austin.)

As a result, KTBC-TV was the only station in Austin until KHFI-TV (channel 42, now KXAN-TV on channel 36) signed on in February 1965. NBC programming continued to be broadcast solely on KTBC-TV for the next 18 months due to contractual obligations. Channel 7 became an exclusive CBS affiliate when all of ABC's programming moved to KVUE (channel 24) when that station first signed on in September 1971.

After Lyndon Johnson became President following the assassination of President John F. Kennedy in 1963, the networks established direct feed lines between KTBC and the various network affiliates in New York City, Dallas and Chicago. This facilitated news reports relayed while the President was residing either in Austin or at his ranch in Johnson City. News reports were also relayed in the president's Oval Office or in his private study at the White House. The Johnsons maintained a penthouse apartment on the fifth floor of the station, which was wired for camera and sound equipment, and used on occasion for local programming on occasions when the Johnsons were away.
