TV Shows That Could Actually Exist in the Same Universe

List RulesRead through the list and vote up the groups of shows that you believe could actually exist in a shared universe

What exactly is a shared universe on television? It’s basically when two or more independent television programs exist within the same world. For example, the character Ursula Buffay appeared in the sitcom Friends as Phoebe’s estranged sister. But before she was on Friends, she also made several appearances as a rather rude waitress at Riff’s on Mad About You. Therefore, we can surmise that Friends and Mad About You exist within the same universe. Since both shows take place in New York City, it’s not really hard to imagine a scenario where Chandler and Joey bump into Paul and Jamie Buchman while taking a stroll down Fifth Avenue. But these sitcoms aren't the only shows that fit this bill - this list is full of TV Shows in the same universe.

There is a same universe TV conspiracy theory called “The Tommy Westphall Universe” that contends every popular American television show exists in the same universe. The theory is based on the finale of the 1980s hospital drama St. Elsewhere, which revealed at the end of the show’s finale that the entire six season series had actually taken place within the child Tommy Westphall's dream. Because St. Elsewhere had crossover episodes with several other shows like Cheers, M*A*S*H, and The Bob Newhart Show, and those shows have crossed over with other shows, a connection can be made that links every one of those programs together.

That same universe television theory may or may not hold water. However, due to television’s fondness for crossover episodes that are produced to boost ratings and bring in a demo audience from one program over to another program, combined with spin-off series, there are several really interesting shows that exist in the same universe. Some are rather obvious like the CSI franchise, while others, like Magnum P.I. and Murder, She Wrote, are more unexpected.

Make your voice heard. Vote up the shared universe theories you think are most likely to be true.

    TGIF Sitcoms

    Thank goodness it's Friday! In the 1990s, ABC started its TGIF programming block, aimed to get young viewers to watch not just one of their Friday night programs, but to watch all of them. The TGIF universe includes: Family Matters, Boy Meets World, Perfect Strangers, Step by Step, and Full House.

    It all starts with Family Matters - a spin-off of Perfect Strangers. From there, the great Steve Urkel, from Family Matters, links up the rest of the sitcoms. Urkel popped up in an episode of Full House, when young Stephanie needed a pep talk about having to wear glasses.  We can also link Urkel to an episode of Boy Meets World, after Urkel sends Corey a chain letter and they become pals. Then, you may remember the episode of Step by Step, when Urkel crash lands at a Lambert family picnic after he strapped on a jet pack that he couldn't quite control.

    Cheers, Frasier, Wings

    The hit sitcom Cheers made its last call in 1993 and spawned the extremely successful spin-off, Frasier, which originally aired later that same year. Frasier lasted for 11 seasons on NBC. That's all pretty obvious, but what most people forget is that those shows share the same universe as Wings, a program created by three former Cheers showrunners.

    Wings takes place in an airport that charters flights out to Nantucket and is often referred to as "Cheers in an airport." The Cheers cast pops up in a couple of Wings episodes. One of the most memorable is when Norm and Cliff fly out of Boston to Nantucket for a fishing trip. The bar buds, however, never make it out of the airport, and instead plant themselves on a couple stools and just chew the scenery.

    King of Queens and Everybody Loves Raymond

    Kevin James was actually a writer and actor on Everybody Loves Raymond before getting a little support from Ray Romano for his own show in 1998. The two CBS shows crossover quite a few times. Ray and Doug become buddies on an episode of Everybody Loves Raymond when Doug helps Ray cheat on his driving test. However, the pair get busted and Doug winds up losing his license. Ray's brother Robert, a police officer, subsequently pulls Doug over, and he gets in trouble for driving without a license. When Doug does get his license back, he gets into a car accident with Ray's dad Frank. It appears that Doug does not have much luck when dealing with the Barone family.

    Ray Romano also pops up in four episodes of King of Queens. All of those episodes are easy to pick out because Ray's name is actually in the title of the episode, like in "Road Rayge.

    Television and film producer extraordinaire Jerry Bruckheimer is responsible for several very successful crime programs on the small screen. Within the Bruckheimer shared universe are CSI, CSI: NY, CSI: Miami, Cold Case, CSI: Crime Scene Investigator, CSI: Cyber, and Without a Trace. However, it's not just the shared forensic nature of the shows that tie them together. There have been several crossover events between the group of shows. Below are just a few.

    In November of 2005, an episode of CSI: Miami concluded on CSI: NY two days later. Jack Malone from Without a Trace guest starred on CSI, and Gil Grissom from CSI appeared on Without a Trace in November of 2007. There has also been a three-way crossover event featuring three of the original CSI programs which aired in November of 2009.
