Reddit AMA Recap: Family Guy writer Steve Callaghan

Last week, Family Guy producer and writer stopped by Reddit to do an AMA right before the 250th episode aired on FOX. The session was short, but Steve DID offer some insight into the show’s past. Check out some of the highlights of the Reddit AMA below:
Changes to the show since Family Guy first premiered in 1999
Great question. The show actually first aired in January of 1999. However, we are in the process of writing and producing our 13th season right now (and airing our 12th), because — as you mentioned — the show was cancelled and off the network for a few years. I think the thing that’s changed the most is both the depth and breadth of the characters. For instance, in Season One, Stewie was mostly just about killing his mother, which was funny for a while, but as we wrote more and more episodes, it was exciting to discover what other layers of him existed (how he was still figuring out his sexual identity, his friendship/rivalry with Brian, etc.). And the same is true for all the other Griffins. But in addition to that, we also have tried to populate the town of Quahog with lots of other fun characters (Mayor West, Dr. Hartman, Tom Tucker, etc.) to fill out the community.
When The Simpsons or other shows rag on Family Guy.
How did the infamous chicken fights come about.
Why only Brian can understand Stewie.
It seemed to make sense from the beginning that since Stewie is a baby, most of the other family members would deal with him like you would a baby. So, for example, in the pilot episode when Stewie says all sorts of horrible things to Lois about how he wants her dead, she gets his general vibe (that he’s crabby), but she doesn’t understand his actual words. And that’s why her response is, “Oh, you want your toy back.”
Check out our review of the 250th episode of Family Guy and it’s too bad because there’s no new episode airing this weekend on FOX. Here’s more of Steve Callaghan’s Reddit AMA session.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
