Wanna feel old? Robot chicken has been on the air since the Bush adminstraion. That's rivaled only by spongebob and family guy which both premiered just as the clinton administraton was ending, and all of them are bested only by the simpsons. Which if you include their premire as tracey ulman show shorts has lasted from the regan administration, bush sr, clinton, w bush, obama, trump, and biden.
And much like those shows or really any long runner especially in animation. The problem is theyve been on so long and are starting to reflect our current culture...sometines a little too closely.
When robot chicken first aired a lot of its humor was targeted to gen x y...maybe some late stage boomers like those born in the 70s. Family guy was kinda right in saying it mostly poked fun at 80s culture like gi joe, transformers, thundercats and he man, with some early 90s humor and ocassionaly a modern joke sketch or two. (W bush as a jedi for ex) but nowadays? There are either a lot more 90s-2000s refferences or more jabs at modern pop culture. And almoat none of the mainstays when it was new, Ocassional shouts not withstanding.
