As some commenters have pointed out already, a distinction has to be made between a conservative cultural output and cultural output produced by conservatives (or libertarians or anti-totalitarians), of which there is a lot more than the former, though it tends to be less explicitly or implicitly political than cultural output of liberals and leftists.
There is actually a not insignificant number of people broadly on the right working in cultural pursuits: people like Robert Ferrigno, Andrew Klavan, Jerry Purnelle, Tom Wolfe, Geoffrey Archer in writing, Jerry Bruckheimer, Adam Sandler, Sarah Michelle Gellar, Jon Voight, Kelsey Grammer in the movies and on TV, numerous country stars, and any one from Alice Cooper and Johnyy Ramone (yes, that Johnny Ramone) to Kid Rock and Avenged Sevenfold in music. All these people tend to be far less conservative in their output, partly because conservatives are generally less inclined to jump on their soapboxes than the left, and partly because culture being such a left-doiminated industry, being a vocal conservative can be a career-limiting position.
