by

The 1980s were a remarkably creative time for television. The decade produced many original and now-classic shows, especially in the science fiction genre. These shows pushed boundaries with fresh ideas or exciting new takes on old favorites, and continue to resonate with audiences today – whether through dedicated fans or recent remakes and reboots.

Here’s a list of the five most influential sci-fi TV shows from the 1980s. Although many memorable sci-fi series existed during that decade, these five shows were particularly groundbreaking and had a lasting impact on television.

Together, these five classic sci-fi shows from the 1980s have a whopping 616 episodes. If you missed them the first time around, there’s a huge amount of great content to discover!

5. V

You might have heard people in power jokingly called “Lizard People.” But do you know where that idea comes from? It originated with the 1983 miniseries V, which, despite only having two parts, was incredibly popular. The first episode drew a massive 40% of all TV viewers! Its success led to a regular V television series the following year. While the series didn’t live up to the miniseries, and wasn’t as well-received, the original V was influential enough to make the entire franchise worth remembering.

V tells the story of when aliens first arrive on Earth, initially appearing friendly and welcomed. However, it quickly becomes apparent they are disguising themselves as humans, hiding a sinister motive. Their planet is failing, and they’ve come to steal Earth’s resources, sparking a war. But the real challenge isn’t just fighting the aliens – it’s figuring out who is truly human and who is in disguise. With its suspenseful plot and shocking revelations, V became a landmark television series, significantly impacting science fiction and popular culture.

Total Episodes: 21 (2 in the miniseries, 19 in the regular series)

4. Mystery Science Theater 3000

Though it first aired in 1988, many people discovered Mystery Science Theater 3000 in the 90s or 2000s. The show began on a local TV station (KTMA-TV, now WUCW) in Saint Paul, Minnesota, and ran for one season before moving to Comedy Central (originally called “Comedy Channel”) in 1989.

Each episode of Mystery Science Theater 3000 (MST3K) features a combination of live actors, puppets, and an old movie. The show’s story revolves around a human who is kidnapped by aliens and held captive on the Satellite of Love. There, a team of eccentric scientists—known as “The Mads”—force the captive to watch terrible films, hoping to find one that will drive them crazy. However, the captive—originally a character played by Joel Hodgson named Joel Robinson—builds robot companions from spaceship materials, and they all watch the movies together. The heart of the show is the host and the robots, seen as dark silhouettes in front of the movie screen, making jokes and playfully commenting on the film—this is called “riffing.” Interspersed throughout the movie are short comedy sketches that add to the show’s humor, satire, and overall story.

Looking back, Mystery Science Theater 3000 really paved the way for a lot of what we see online today. Things like watching people react to videos on YouTube, live-streaming, and even hosting watch parties all have roots in MST3K. It was one of the first shows to popularize the idea of commenting on movies, and it influenced a whole generation of content creators.

3. Knight Rider

I’ve always loved sci-fi, and I know it usually appeals to a dedicated group of fans who enjoy its deep dives into science or wild imagination. But it’s really tough to make a sci-fi show that everyone loves. That’s what made Knight Rider from 1982 so special – it broke through and became a global hit, capturing the attention of audiences everywhere!

This show perfectly captures the spirit of 1980s television, mixing action, spy stories, crime dramas, and science fiction. It centers on Wilton Knight, a wealthy man who saves the life of Detective Michael Long (played by David Hasselhoff) after a near-fatal shooting. Knight reconstructs Michael’s face with advanced surgery and gives him a new identity as “Michael Knight.” He then recruits Michael to lead FLAG (Foundation for Law and Government), a private organization dedicated to fighting crime. Michael is partnered with KITT, a highly advanced, armored car equipped with weapons and controlled by artificial intelligence. Together, Michael, KITT, and the FLAG team tackle dangerous missions against terrorists and global threats that require a unique and powerful approach.

Few shows defined the 1980s quite like Knight Rider, with its unforgettable theme song, David Hasselhoff’s rise to fame, and KITT becoming a pop culture phenomenon. Looking back now, the series almost seems to have predicted our current world – one where wealthy individuals attempt to influence society, often with the help of highly advanced, computer-powered vehicles.

2. Quantum Leap

With a title that screams science fiction, Quantum Leap arguably has the most fitting name of any show from the 1980s. Although it first aired in March 1989—almost slipping into the 90s—and gained most of its popularity later, it was still created with the energy of the 80s and deserves to be included.

The show centers around Dr. Sam Beckett, a brilliant physicist played by Scott Bakula, who works on a top-secret time travel project in the near future. After spending a huge amount of government money trying to prove time travel is possible, Beckett impulsively tests the machine on himself when the project is about to be shut down. He successfully travels through time, but with an unexpected twist: he appears as a different person to everyone he meets – someone from the past who needs his help to fix a problem. Only Beckett sees his true self, reflected in mirrors.

Dr. Sam Beckett isn’t alone on his journey through time. He’s guided by a holographic projection of his best friend, Admiral Al Calavicci (played by Dean Stockwell), who’s linked to the show’s powerful AI computer, nicknamed “Ziggy.” Together, they work to correct disruptions in history, help Sam regain his lost memories, and ultimately find a way for him to return to his own time. Quantum Leap often showed Sam impacting major historical events, sometimes even inspiring famous people and their accomplishments. The show became a beloved classic of science fiction, so much so that NBC attempted a reboot in 2022. While the new version was a good sci-fi show, it didn’t quite capture the unique, quirky charm of the original series.

1. Star Trek: The Next Generation

There’s no question that Star Trek: The Next Generation is the most significant science fiction TV show of the 1980s, and for good reason. It faced the huge challenge of following the original Star Trek, a truly groundbreaking and influential series. It then had to win over an audience that was either deeply devoted to the original or completely unfamiliar with the franchise. This was particularly difficult in the late 1980s, when audiences were more skeptical about the future. The optimistic vision of the original Star Trek had resonated with the counterculture of the 1960s, but the focus on consumerism and wealth in the ’80s felt like a direct contrast to what Star Trek: TNG represented.

Despite facing challenges, Star Trek: The Next Generation and its memorable cast achieved remarkable success, becoming a highlight of both the Star Trek franchise and the science fiction genre. Living up to its name, The Next Generation attracted a new wave of fans and proved incredibly popular during its original run (1987-1994). It launched a series of subsequent Star Trek shows – including Deep Space Nine, Voyager, and Enterprise – which kept the franchise thriving for over ten years. Star Trek: TNG’s influence continues to be felt in the modern series, as seen in the sequel Star Trek: Picard. Even today, it remains a significant part of popular culture, with clips and moments frequently shared as memes and GIFs online. Few sci-fi shows can match Star Trek: The Next Generation’s impact; many of its best episodes have become foundational for the genre, continuing to inspire and influence storytelling today.

Total Episodes: 178 (7 Seasons)
