I know you can probably find these all online, but if anyone's interested in watching them on TV, H&I has Batman, Superman, and Wonder Woman every weekend. I found out because they also have Star Trek 8pm - 12am every weekday (one episode per series), and I fell asleep with the TV on and woke up to some classic Batman.
*yes i know that these aren’t all the shows on those channels it’s just the ones i have memories of watching while growing up. make your own poll about it
