My siblings and I watched Looney Tunes growing up. This was before I was aware there was such a thing as cartoons for adults. Adults wouldn't really watch Looney Tunes, except when they were with us.
This was in the 1990s, but Looney Tunes started in the 1930s. Moreover, it is quite violent. I would think twice before showing it to a child today. Besides the beating with blunt weapons and dynamite explosions, there are multiple veiled references to rape, and at least one instance where Yosemite Sam proposes to "draw and quarter" Bugs Bunny. Check out that term on Wikipedia.
My question is: In the heyday of Looney Tunes, in the 1940s and 1950s, was it considered an adult or a kids cartoon?
