Family Guy creator Seth MacFarlane credits The Simpsons with changing the course of his career.
Speaking to Entertainment Weekly, MacFarlane - who worked for Hanna-Barbera prior to creating Family Guy - wanted to be a Disney animator until he saw The Simpsons.
"[Matt Groening's] show redirected the course of where I wanted my professional life to go," MacFarlane said.
"I wanted to be a Disney animator, and then The Simpsons came out, and in every way - writing-wise, production-wise, timing-wise, animation-wise - it just rewrote the rulebook. Suddenly I was laughing out loud at cartoons.
"I was doing stand-up at the time and I loved it, and I thought, 'It's too bad there isn't a way to do adult humour in cartoons'. And they just opened that door for everybody.
"That show came out and I remember thinking, 'Oh my god, this is what I want to do'. It's like All in the Family. It's that degree of altering the landscape."
