KERA, the Dallas PBS station, was the first U.S. station to broadcast Monty Python’s Flying Circus.
KERA-TV began showing the programme in the United States in 1974, helping expose American audiences to a British comedy series that had already finished its original BBC run. The station’s programming director, Ron Devillier, played an important role in bringing the show to Dallas and recognizing its appeal beyond conventional public-television fare.
KERA’s broadcasts helped create the American following that later made Monty Python a cultural phenomenon. Other PBS stations, including outlets in major cities such as Boston, Los Angeles, and New York, subsequently carried the series. That wider public-television circulation came before ABC attempted to package selected episodes as edited commercial-network specials.
The answer is sometimes confused with a large-market PBS station because several stations became important early broadcasters. The question asks for the first Dallas station, however, making KERA the canonical answer rather than KCET, WGBH, or WNET.
