Pplenty of people seek out 'source material' to display on their vintage TVs; if you're after such stuff I point you at:
http://publicdomainmovies.net/
where there are hundreds of hours of movies etc to download and view at your leisure. Lots of great 1950s sci-fi B-movies so you can re-live those hiding-behind-the-sofa-while-the-heroine-gets-devoured-by-a-giant-squid moments!
