You can rent/stream all the space content you want on different platforms, so why lament what other people are watching, or what type of programming dominates X or Y channel? "Hey why can't the Food Network have more Space stuff?" "Too many rednecks and not enough aliens on the Weather Channel!"
Also there was once a show called Rocket City Rednecks about a redneck who actually worked for NASA. So there!
And for someone so concerned about space pop-culture and how it relates to public interest in space travel, you don't seem as concerned about the real nuts-and-bolts science or the researchers and engineers who actually work in these fields. If you went down that path, there would be more doors opening up for you to learn about, so many that you'd no longer care about public interest in rednecks or some Sci-Fi TV show's popularity.
EDIT: THere's also BOOKS. Not just video games and movies. Books can float in space!
