"What would the entertainment industry look like if it were as conservative as it actually is liberal?" is an interesting counter-factual. Most "conservative media" I've seen has been terrible, but I think that's partly because it's too overtly ideological and didactic to be good art.
If you're looking for it, you occasionally run across good examples of high-quality media that incorporate a conservative worldview. Craig Zahler's movies obviously fit this category, as do a lot of Tarantino movies. Old Fox programs like The Simpsons and especially King of the Hill were weirdly criticized by conservatives at the time but are downright reactionary when viewed today. Some of the pre-woke Disney stuff, like The Incredibles, could qualify too. My best guess is that in a world dominated by conservatives, we'd probably see more titles like this. In other words, the industry would look pretty similar but the points of emphasis would change a little.
