KXAN-TV is the NBC-affiliated television station for Austin, Texas. It broadcasts a high definition digital signal on UHF channel 21 (PSIP virtual channel 36) from a transmitter in the West Austin Antenna Farm north of West Lake Hills. Owned by the LIN TV Corporation, the station is sister to MyNetworkTV affiliate KBVO and CW affiliate KNVA. All three share studios on West Martin Luther King Junior Boulevard between the Clarksville section of Austin and the University of Texas at Austin campus. Syndicated programming on KXAN includes: Wheel of Fortune, Jeopardy!, The Doctors and Rachael Ray.

The station first went on-the-air on February 12, 1965 as KHFI-TV, originally broadcasting on channel 42. It was owned by the Kingsbury family along with KHFI radio (AM 970, now KLGO at 99.3 FM; and 98.3 FM, now at 96.7). KHFI was the second television station in Austin, signing on a little more than twelve years after KTBC-TV (channel 7).

It logically should have signed-on as Austin's NBC station, since up to that time all three networks had been shoehorned on KTBC, a primary CBS affiliate. However, due to contractual obligations, it spent more than a year and a half as an independent before joining NBC in 1966. Unlike most affiliates with the network in then two-station markets, KHFI did not take on a secondary ABC affiliation. The Kingsburys would later bring in Henry Tippie as a partner, and in 1973 were granted FCC permission to move KHFI-TV to channel 36.

Kenneth Foster, Jr. (born October 22, 1976) is a prisoner formerly on death row in Texas, convicted under the law of parties. He was convicted of murdering Michael LaHood in August 1996. His conviction and execution were contested because he was convicted under a law of parties, not for physically committing the crime.

Texas Governor Rick Perry commuted the death sentence to life imprisonment only three hours before the execution was scheduled to take place on August 30, 2007. Kenneth Foster, Jr. will be eligible for parole in 2037. He is currently located at the Byrd Unit of the Texas Department of Criminal Justice to be reprocessed as a general population prisoner.

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.
