Congratulations! You just disproved the theory that Americans (and especially us Texans) are the most arrogant people on Earth!
Talk about misinformed. We didn't "find it 20 years later". I'm 50. I watched Benny Hill and Monty Python with my folks in the 70s. I watched Red Dwarf in the 80s and 90s on PBS here in Houston. On November 8 I bought Red Dwarf series XI on blu-ray, less than two weeks after it finished airing in the UK.
In the summer of 1974, Ron Devillier, the programme director for nonprofit PBS television station KERA in Dallas, Texas, started airing episodes of Monty Python's Flying Circus. Ratings shot through the roof, providing an encouraging sign to the other 100 PBS stations that had signed up to begin airing the show in October 1974—exactly five years after their BBC debut.
