25 Gunsmoke (1955-1975)

CBS Television

Television technically dates back to 1928, when General Electric tested their early 48-line TV system with a play called The Queen's Messenger. However, it was Gunsmoke that truly brought television drama to new heights. While there were other shows like The Texaco Star Theatre, Your Show of Shows, and You Bet Your Life, as well as sitcoms like Mama and dramas like The Lone Ranger and Martin Kane, Private Eye, it was Gunsmoke that found its stride on television.

The first episode was introduced by none other than John Wayne, who described it as "honest, adult, and realistic." The episodic western drama followed Marshal Matt Dillon and his sidekick Chester as they protected Dodge City from various threats.

Gunsmoke was considered "adult" for its time, addressing mature themes like brothels, murder, alcoholism, sexual assault, and featuring one of the first television antihero protagonists. It became a hit show, dominating television ratings for many years during its 20-year run and continues to be influential today.

7 M*A*S*H (1972-1983)

20th Television

Originating from the Robert Altman film, M*A*S*H achieved unparalleled success. Its finale was watched by more people than any other scripted TV show in history. It seamlessly blended humor, drama, and sociocultural relevance, using its Korean War setting to reflect the realities of the Vietnam War.

M*A*S*H followed a group of likable medics stationed in South Korea. The show was resolutely anti-war and didn't shy away from acknowledging the atrocities of war, especially those committed by America's military-industrial complex.

With a mix of medical drama, romance, wit, and character studies, M*A*S*H remained a top show for a decade and is synonymous with the greatness of American TV.

17 The Mary Tyler Moore Show (1970-1977)

CBS

While I Love Lucy was widely loved, The Mary Tyler Moore Show marked a significant turning point in pop culture's recognition of second-wave feminism. The show defied norms with its poignantly funny and daring portrayal of an independent woman without a husband or children. Mary Tyler Moore's character was dangerously subversive at the time, inspiring women to pursue their dreams.

16 The Muppet Show (1976-1981)

Henson Associates

Amidst a sea of programs targeting youth, The Muppet Show managed to capture both children and adults. It brought wit, charm, and a touch of irreverence that resonated with audiences. The Muppets weren't perfect role models, but their self-acceptance journeys encouraged kids to embrace their own uniqueness.

15 Roots (1977)

Wolper Productions

Roots captured the attention of 100 million viewers and received numerous Emmy Award nominations. It tackled the taboo topic of slavery and shed light on the horrific truths surrounding it. Roots' masterful storytelling and character development prompted the country to reflect on its past and consider atoning for its injustices.

6 Seinfeld (1989-1998)

Castle Rock Entertainment

Seinfeld, often hailed as one of the greatest sitcoms, stood out by defying traditional sitcom conventions. It showcased the mundane, often absurd aspects of everyday life in New York City. The show's ability to weave multiple storylines and mercilessly mock its characters made it a staple of popular culture. Seinfeld's postmodern, super-ironic approach to comedy remains timeless, despite some viewers finding the finale disappointing.

21 Married... With Children (1987-1997)

Fox

Married... With Children presented a stark contrast to the picture-perfect families typically seen on TV. The Bundys, a dysfunctional suburban Chicago family, brought biting humor and acidic comedy to the screen. The show explored the constant verbal sparring between the husband, Al Bundy, and wife, Peggy, as well as their struggles with money, success, and intimacy. Its relatability made it a memorable part of television history.

12 'Star Trek: The Next Generation' (1987-1994)

10 The Larry Sanders Show (1992-1998)

Columbia TriStar Domestic Television

Garry Shandling created one of the most groundbreaking comedy series of all time with The Larry Sanders Show. It deconstructed the conventions of conventional sitcoms and dove into the behind-the-scenes world of late-night television.

11 The X-Files (1993-2018)

Fox

The X-Files captured the spirit of the 1990s like no other show.

Deadwood, an HBO production, is an extraordinary feat in TV production. It portrays the lawless town of Deadwood during the late 1800s, blending elements of historical drama, Western, and crime genres. The show's strong ensemble cast, profanity-laden dialogue, and beautifully crafted storylines set it apart. Despite its cancellation after three seasons, Deadwood remains a revered work of television art.

12 South Park (1997-)

Comedy Central

If South Park may seem less edgy nowadays, it's because there are numerous copycat shows that have been influenced by its humor and approach. This can obscure the fact that South Park is truly significant, hilarious, and unique. Dissimilar to other scripted shows, Trey Parker and Matt Stone approach South Park like a news show, creating and animating each episode within a week to remain topical and current. It's a challenging and bonkers approach, as depicted in the documentary 6 Days to Air, but the result is a show that often tackles relevant cultural issues better than any other comedy.

South Park follows a group of perpetually young boys and their parents in a Colorado town. Over the past 25 years, the show has tackled a wide range of issues and ideas. The most controversial episodes of South Park remind us that we can still be shocked in the modern age. Despite the passage of time and the release of new specials on Paramount, such as the feature-length Streaming Wars, South Park remains boldly provocative, while also being thought-provoking, intelligent, and undeniably funny.

14 'Better Call Saul' (2015-2022)

Image via AMC

Better Call Saul, a prequel and spin-off of Breaking Bad, is often considered to have surpassed its parent show. The series focuses on the character of Saul Goodman before he adopts the persona audiences know from Breaking Bad. For the majority of Better Call Saul, he goes by the name Jimmy McGill, and the show explores his transformation into Saul Goodman.

The pace of Better Call Saul is slower compared to Breaking Bad, but it rewards patient viewers with gradually increasing tension, leading to a powerful sixth and final season. It has achieved similar popularity to Breaking Bad and stands as one of the few TV spin-offs that is on par, or sometimes even better, than its predecessor.

20 Hannibal (2013-2015)

NBC

Bryan Fuller's adaptation of Thomas Harris' famous novels, Hannibal, is an artistic and loosely-based series that aired on basic cable.

The show offers a rapid-fire, often absurd look into the lives of a once-wealthy family who have fallen from grace after the arrest of their patriarch. With its consistently brilliant sociopolitical commentary and silly puns, Arrested Development was canceled after three seasons on Fox but later revived on Netflix due to its dedicated fan base.

The show follows the journey of the titular character as she fulfills her destiny as a demon fighter, navigates love and friendships, and transitions from high school to adulthood. While not every episode hit the mark, the best moments of Buffy the Vampire Slayer were unparalleled in terms of quality and impact.

18 'Justified' (2010-2015)

While Elmore Leonard adaptations are more common in film, Justified proved that his style translates well to serialized TV. The show, which ran for six seasons, follows a US Marshal who returns to his hometown of Harlan County and dispenses his own brand of justice. Justified stands out among the vast array of crime/thriller shows due to its compelling characters and superbly written dialogue.

The series, created by Vince Gilligan, revolves around a seemingly ordinary high school chemistry teacher, Walter White, who turns to manufacturing and selling methamphetamine. Breaking Bad explores themes of transformation, morality, and the consequences of one's actions. It concluded after five seasons, defying the traditional rule of stretching a show's longevity, and inspired a new wave of masterful storytelling in the medium.
