Tom and Jerry was created back in the 40s
I liked them.  Are there reruns anywhere?
The original run had 115 episodes through 1958.
Where can I watch them now since they are not produced any longer?
Shorts have been released on home media since 1990s.
If you were to watch them now, was the language politically correct?
Possibly. It won seven academy awards for Animated Short Film.
When was the last award?
Not since the original studio closed in 1957.
Can you buy them on dvd from Amazon?
