Enyart is being sued for trademark infringement and cybersquatting in New York state and federal courts by the NPR show's producers at ScienceFriday Inc.
Representatives of the show "Science Friday," hosted by journalist Ira Flatow, say the similarity in names is confusing people and sometimes diverting them to Enyart's website, kgov.com.
Enyart is the self-described fundamentalist Christian pastor of the 60-member Denver Bible Church. He believes the world's age is measured in thousands, not billions, of years because the Bible tells him so and, he said, scientific evidence backs it up.
Imitation, in this case, is the sincerest form of challenge, Enyart said. His science-talk show started in 1991, but he renamed it "Real Science Friday" in 2006 to push back against mainstream science journalism.
