You know how when you watch old shows on TV and there's those logos after the ending credits? Those are the distributors, you contact those companies. Viacom, Sony Pictures Classics &c. I already have three or four retro channels on real TV here plus tons of stuff on youtube and other places, you're better off making your own stuff than competing in this already crowded market. But you don't sound like you have much motivation, skill, knowledge, experience, equipment, or other resources so good luck.
