For twenty three years, longer than some of the readers of this site have been alive, one of the greatest mysteries on television has carried on with little to no hints as to the truth. Everyone knows who shot JR. Everyone found out the secret behind Twin Peaks.

The Cylons were revealed in Battlestar Galactica. We even all found out just where the survivors ended up in Lost. But no answer was harder to come by than which Springfield the Simpsons actually lived in.

For years, people tried to piece together the landmarks of Springfield and find out just where the Simpsons lived. Which city in the United States out of the 38 cities, towns and townships named Springfield had its own nuclear power plant, gorge, glacier and national forest that was also within driving distance to New York City? People quickly learned the answer is none, but that didn’t stop people from questioning where the Simpsons took place.

When talking to the Smithsonian Magazine, Groening was asked about the generic nature of the name Springfield. Groening replied that, “Springfield was named after Springfield, Oregon. The only reason is that when I was a kid, the TV show Father Knows Best took place in the town of Springfield, and I was thrilled because I imagined that it was the town next to Portland, my hometown.

When I grew up, I realized it was just a fictitious name. I also figured out that Springfield was one of the most common names for a city in the U.S. In anticipation of the success of the show, I thought, ‘This will be cool; everyone will think it’s their Springfield.’ And they do.”

The Simpsons are the kings of prime time animation. Lasting an astounding twenty-three seasons and counting, The Simpsons is an institution that has spanned generations. So the collecting of these episodes is something that fans have enjoyed since the earliest days of TV on DVD. Fox has been releasing these sets for over a decade now and we find ourselves in an interesting era of the show.

Most people consider these early and mid 2000s seasons of the show to be the worst era during the impressive run. The show seemingly was stale and the spark was missing. At the end of the day the show survived and has since rebounded to become a relevant, often hilarious show.

One of the things I was most excited about when I dug into this set was the plethora of special features. The Simpsons sets have always set the standard for insightful and worthwhile special features, anchored by the amazing cast and crew commentaries that have accompanied every single episode since season one, making over 300 episodes worth of anecdotes, insights and inside knowledge of the creation of an institution.

I was thinking about long running TV shows the other day and having a discussion with some colleagues. We were impressed to realize that The Simpsons has been on the air for 22 years. That’s longer than some staffers on this site have been alive. Amazing.

Well, the amazing can now continue because Fox has officially given the green light for a 23rd season of the venerable animated comedy featuring Homer, Marge, Lisa, Maggie, Bart and their host of friends and neighbors in beautiful Springfield. The 23rd season will get the show to the impressive 500th episode milestone and then beyond, bringing the total number of episodes to 515. That’s a lot of chalkboards and sofa gags.

“Like many 22-year-olds, The Simpsons is extremely happy remaining at home, on Fox, and hopes it doesn’t have to go out into the real world for many years to come,” said The Simpsons executive producer Al Jean. I’m sure that’s true because, really, what a great gig it must be for the people who make the show.

Sure, it might get a bit tiring doing the same thing for 22 years but in Hollywood, this kind of lengthy work doesn’t come along all that often — especially if your show happens to be on the Fox network. Just ask Joss Whedon.

As an added bonus, I dug up a video of The Simpsons first season opening credits. It’s fun to see how the characters and situations have changed but also stayed remarkably the same as well. Check it out after the jump.

Far-gone are the days when networks held enough power and importance to have TV crossovers and intermixing story lines, much like the days when George Reeves would pop up on I Love Lucy or story lines interweave between Buffy and Angel. Fox seems to be the only network with interest in doing such stunts, as Family Guy’s Stewie popped up on an episode of Bones.

Well, it looks like Fox is doing it once again with an announcement for a Simpsons on-air scavenger hunt in celebrating 20 years of broadcasting TV’s favorite animated family. In a press release, the network announces that it will start on November 9th, and go for an entire week.

FOX is paying “homage” to 20 years of television’s favorite yellow family with the network’s first-ever on-air scavenger hunt. Beginning Monday, Nov. 9 and continuing through Friday, Nov. 13, fans can watch FOX each night to find SIMPSONS shout-outs, tributes and clues featured in primetime programming and on-air promos.

One lucky winner will receive the ultimate SIMPSONS prize package, including a trip for two to Los Angeles to attend a SIMPSONS table read with the Emmy Award-winning voice cast and producers, a home entertainment system, SIMPSONS DVDs and merchandise and tickets to Universal Studios Hollywood, home of The Simpsons Ride.

Anybody over the age of 13 can participate, and once they catch the shout-out, be sure to visit www.fox.com/scavengerhunt each night to test their knowledge and download some pretty cool Simpsons goodies. The contest officially starts after next week’s episode of Simpsons, so be sure to keep your eyes peeled!
