So the world of the 25th Century seems to be experiencing a strong wave of Boomer Era nostalgia, which I heartily approve of. Captain Mercer seems to be particularly into it, with his Kermit the Frog totem, his love for Billy Joel, and his taste in movies. And, based on the chip that he handed Krill Woman at the end, they still use physical media in the far future-- which means I'll have to buy the White Album again.
I had an idea that due to further Disney extensions to public domain laws these songs and movies are just now entering the public domain for the first time by the time of the Orville so that's why there is a renaissance of vintage material. Maybe new IP has become prohibitively expensive in the future.
