What year did Tom and Jerry end?

It's impossible to say definitively that Tom and Jerry "ended" because the franchise has continued in various forms over the years. Here's why:

* Original Theatrical Shorts: The original series of Tom and Jerry theatrical shorts, produced by MGM, ran from 1940 to 1967. However, they didn't stop there entirely.

* Hanna-Barbera Productions: After MGM, the duo continued in various formats, including TV series, specials, and even some theatrical shorts produced by Hanna-Barbera from 1961 onwards.

* Warner Bros. Era: In 2006, Warner Bros. took over the franchise and has produced new Tom and Jerry content ever since, including animated films, TV shows, and even a live-action/animated hybrid film.

Therefore, while the original MGM era ended in 1967, the Tom and Jerry franchise is still very much alive today.
