Seth MacFarlane created hit animated TV shows like “American Dad” and “The Cleveland Show,” but “Family Guy” is the original and most successful. Although it first aired in 1999, did you know it was canceled and then revived because of fan responses?

Here are 9 things you didn't know about "Family Guy."

Most episodes have two versions

In spite of its name, “Family Guy” is not what you would consider a family-friendly TV show. For every episode that airs on network television, there’s an uncensored version available only on the full-season DVD.

Brian is very similar to his creator, Seth MacFarlane

Though MacFarlane provides voices for many “Family Guy” characters, he shares more similarities with Brian than any of the others. The Griffin family dog and MacFarlane share the same speaking voice and a lot of the same worldviews, according to MacFarlane.

“Family Guy” has won 8 Emmys, despite the jokes

It was the first animated series since ”The Flinstones” in 1961 to be nominated for Outstanding Comedy Series in 2009 when it lost to “30 Rock.” The series has won Emmy awards for individual performances, Music Composition for a Series, and Sound Mixing for a Comedy or Drama Series, among others.

Fans refused to let the show die

“Family Guy” was canceled twice during its first few years – once in 2000 before a last-minute order for 13 episodes and again for good in 2002. After Cartoon Network received sky-high ratings for airing “Family Guy” re-runs and the sales of the series on DVD surged to 3 million copies, Fox brought the popular show back one last time in 2005 and it’s been on ever since.

Quagmire’s appearance is based on Bob Hope

Have you ever wondered why Quagmire looks so familiar? He bears an uncanny resemblance to vaudeville comedian, Bob Hope.

Quagmire is a baby boomer

According to his driver's license, Quagmire was born in 1948. It's probably best if we don't ask how he stays so youthful, though.

MacFarlane Was 24 When Family Guy First Aired

At the time in 1999, he was the youngest executive producer in TV history.

George Lucas Loves Family Guy

There’s a reason “Family Guy” can get away with all the “Star Wars” jokes. Creator George Lucas loves the show and when MacFarlane’s staff reached out to him, Lucas gave them permission to use any of his characters as long as their appearance is accurate.

The main cast makes major bank

“Family Guy” owes its success to both the excellent writing and the superb voice cast. As a result, each member of the main cast makes about $225K per episode.
