Television is a universal passion. From animated series and news updates to dramas and sports, we indulge in it all. At times, it feels like people are endlessly captivated by TV. The 21st century has transformed the industry with streaming platforms, an abundance of shows, and larger budgets; we even have series about the making of TV shows.
Binge-watching full seasons has become a beloved activity. Viewers argue whether to watch episodes weekly or wait to devour an entire season at once. The global pandemic and lockdowns further solidified our TV-centric culture, where shows are consumed voraciously. With the rise of social media, TV characters and their memorable lines have become cultural icons. Here are the most iconic television shows of the 21st century.
10. Battlestar Galactica (2004–2009)

In an age of reboots, this sci-fi classic from the late 1970s, reimagined for the modern era, is hailed by many as the pinnacle of the genre. Fans adore its realistic portrayal of space battles and its exploration of political and religious themes. Battlestar Galactica presents balanced perspectives on issues like military overreach and the sacrifices made for collective survival.
Beyond addressing complex themes, this series introduces enhanced Cylons. These artificial beings, originally designed by humans for servitude, rebelled and annihilated humanity's 12 colonies, claiming, “they have a plan.” The show garnered widespread praise and numerous accolades, including a Peabody Award and the Television Critics Association’s Program of the Year Award.
9. The Big Bang Theory (2007–2019)

For 12 seasons, viewers were entertained by the quirky adventures of theoretical physicist Sheldon Cooper and his circle of friends. This geek-centric sitcom focuses on the personal and romantic lives of a group of scientists in California. The characters, with their distinct behavioral quirks, often find themselves in socially awkward scenarios. Alongside the humor, the show delves into their personal growth and mutual support. Jim Parsons’ performance as Dr. Cooper earned him four consecutive Emmys for Outstanding Lead Actor in a Comedy Series from 2011 to 2014, during which the show also received nominations for outstanding comedy series.
The series boasted an impressive array of guest stars, from Kathy Bates to Stephen Hawking and many more. One of its most appealing features is its episodic format. Unlike many modern shows with season-long arcs, The Big Bang Theory allows viewers to enjoy each episode independently, ensuring Sheldon remains his brilliant yet naive self, regardless of missed episodes.
8. Grey’s Anatomy (2005–Present)

This enduring series follows Meredith Grey, a determined surgical intern. The title pays homage to the renowned 1858 anatomy textbook Gray’s Anatomy by Henry Gray. Launched mid-season in 2005/06, this medical drama has become a cultural phenomenon, now in its 19th season. Created by Shonda Rhimes, it holds the record as the longest-running medical drama and the most-watched post-Super Bowl drama in television history.
For years, it has been ABC’s top-rated show, leaving a lasting impact on pop culture. Grey’s Anatomy has earned numerous accolades, including a Golden Globe for Best Television Series–Drama and 38 Primetime Emmy nominations, with two for Outstanding Drama Series. The series is likely to return for a 20th season.
7. The Wire (2002–2008)

Over five seasons spanning six years, HBO audiences followed Detective Jimmy McNulty’s journey. Created by author and former police officer David Simon, the series is loosely based on Simon’s colleague, retired homicide detective Ed Burns. The Wire is celebrated as one of the most raw, authentic, and critically praised crime dramas. Unlike traditional cop shows, it often critiques the system it portrays.
Rather than glorifying individual heroism within a broken system, the series exposes systemic corruption and its frequent failures. In a BBC poll, over 200 critics hailed The Wire as the greatest TV series of the 21st century. The show masterfully blurred moral lines, avoiding the pursuit of longevity. Its creators aimed not for the longest run but for the best quality, and many agree they crafted the finest crime drama ever made.
6. Chapelle’s Show (2003–2006)

Dave Chapelle skyrocketed to fame with his unique sketch comedy on one of Comedy Central’s most acclaimed shows. His program pushed the envelope on sensitive subjects, particularly race. Chapelle’s career has been remarkable; early in his stand-up days, he was famously booed offstage at Harlem’s Apollo Theatre. Yet, in 2019, he was honored with the Mark Twain Prize for American Humor.
After modest successes like the 1998 film Half Baked, Chapelle finally showcased his full potential. By the end of its third season, his show had become a cultural phenomenon, with fans eagerly quoting it and craving more. Then, Chapelle walked away, sparking media frenzy. He later appeared on Oprah Winfrey’s show to explain his departure, citing his social responsibility. He acknowledged that while his sketches were humorous, they risked conveying harmful messages about race.
5. Lost (2004–2010)

Debuting on September 22, 2004, Lost captivated 18.6 million viewers in its pilot episode. The show quickly amassed a devoted fanbase, following the survivors of the fictional Oceanic Flight 815, which crashes on a mysterious island filled with supernatural elements, power struggles, and even polar bears. Lost mastered the use of flashbacks, flash-forwards, and sideways narratives, featured a diverse cast, and consistently hinted at looming dangers. Even today, fans debate the show’s unresolved mysteries, such as Walt’s connection to the island and its apparent ability to move.
While some viewers were frustrated by the ambiguous ending, others appreciated the show’s openness to interpretation. Many fans hoped for a seventh season, confident that audiences would continue to watch. However, the creators believed the story and characters were best served by concluding after six seasons. The series garnered numerous awards, inspired extensive fan fiction, and even has its own dedicated encyclopedia, Lostpedia.
4. Mad Men (2007–2015)

This period drama centers on the Sterling Cooper advertising agency located on Manhattan’s Madison Avenue. The “Mad” in Mad Men is clarified in the pilot episode as an abbreviation for Madison. The story concludes at the newly formed Sterling Cooper Draper Pryce, a fictional firm. Praised for its intricate portrayal of 1960s New York City social dynamics, the series follows protagonist Don Draper, his career, colleagues, and personal life from 1960 to 1970. As the show progressed, it delved deeply into the multifaceted lives of its characters, exploring their professional and personal challenges.
The series captivated audiences with its realistic depiction of gender roles in 1960s America. It highlighted the struggles of an older generation adapting to a rapidly changing, youth-driven society. Airing on AMC for seven seasons and 92 episodes, the show won multiple accolades and is widely regarded by critics as one of the finest television series ever made.
3. The Daily Show (1996–Present)

The sole entry on our list that began in the 20th century and the only news-centric program is The Daily Show. While the series humorously critiques various news outlets, it remains a primary source of political commentary for many Americans. Originally hosted by Craig Kilborn, it debuted on July 22, 1996. Kilborn departed in December 1998, and Jon Stewart assumed hosting duties on January 11, 1999. Stewart’s tenure, marked by sharp political satire, lasted until 2015, when he passed the torch to Trevor Noah.
Across its three hosting eras, the show has earned 24 Primetime Emmys. Despite its satirical tone and eccentric correspondents, it remains a news program at its core. It resonates with millions of Americans disillusioned with traditional politics and eager for innovative perspectives. Trevor Noah’s run concluded on December 7, 2022. Comedy Central has introduced a rotation of guest hosts, including Sarah Silverman, to maintain the show until a permanent host is selected.
2. Breaking Bad (2008–2013)

Debuting in January 2008, this series follows Walter White, a high school chemistry teacher diagnosed with terminal lung cancer. To secure his family’s future, he turns to manufacturing and selling methamphetamine, partnering with a former student. Despite their morally ambiguous personas, the characters are so compellingly written and acted that viewers are drawn into their journey. The show ran for five seasons and 62 episodes, with the film El Camino, released six years later, addressing unresolved plot points.
Breaking Bad garnered numerous accolades, including 16 Primetime Emmys, two Golden Globes, two Peabody Awards, and four Television Critics Association Awards. Bryan Cranston’s portrayal of Walter White earned him four Primetime Emmys for Outstanding Lead Actor in a Drama Series, while his co-stars also received widespread recognition. The show’s exceptional writing, acting, character development, and precise storytelling cemented its status as one of the 21st century’s greatest series.
1. Game of Thrones (2011–2019)

Despite its controversial finale, this series remains one of the most iconic and cherished shows of all time. Game of Thrones served as HBO’s flagship program for eight years, inspiring a spin-off and more in development. Adapted from George R.R. Martin’s A Song of Ice and Fire, the show was filmed across England, Canada, Croatia, Iceland, Malta, Morocco, and Spain. These stunning locations brought to life the fictional realms of Westeros and Essos, following the power struggles of Houses Stark, Lannister, Baratheon, and others.
Game of Thrones is a fantasy epic featuring magic, dragons, political intrigue, religion, and warfare. It’s akin to Dungeons & Dragons brought to life, complete with Sean Bean’s infamous beheading. The series earned 59 Primetime Emmy Awards, the most for any drama, including Outstanding Drama Series in 2015, 2016, 2018, and 2019. However, these accolades couldn’t shield it from the widespread criticism over its divisive ending.
