(CNN) — And they say TV’s not good for you.

It was through a television screen that most people witnessed the 1969 lunar landing and Martin Luther King Jr.’s “I Have a Dream” speech. Together, viewers saw firsts like Mister Rogers sharing a foot bath with his Black policeman neighbor, Officer Clemmons, on a hot day. They listened as Whitney Houston’s transcendent voice soared through “The Star-Spangled Banner” during her iconic Super Bowl performance in 1991.

These and more indelible moments appear on the Television Academy’s new list of the 75 most impactful moments in TV history, spanning introductions, endings and history-making events.

Released in conjunction with the 75th Annual Emmy Awards, the list includes moments from every decade, from the premiere of “Meet the Press” in 1947 to an emotional episode of “The Last of Us” that aired just last year.

As we know, TV isn’t just a medium for entertainment, and many of the moments on these list speak to larger chapters in our history. The response to the footage of George Floyd’s murder, which in 2020 inspired activists to protest anti-Black racism and police violence, showed how challenging and influential the medium can be.

TV can be a point of connection, too, inspiring conversations about a silly gag on “I Love Lucy” at the office water cooler or gobsmacked tweets about the shocking ending to an episode of “Game of Thrones.”

Although our relationship with television and its technology has changed drastically over the last few decades, this list is proof that the medium continues to engage and inspire us.

Moments of history in the making

With the advent of national broadcast news shows in the 1950s, viewers no longer had to wait until the next morning’s newspaper dropped on their doorstep to watch history unfold. The evening news in the 20th century offered a window to world-altering events: In 1969, an estimated 650 million people watched a blurry image on their TV sets as Neil Armstrong walked on the moon.

Live news coverage has shepherded viewers through unimaginable tragedies like the September 11th terrorist attacks in 2001 and the Space Shuttle Challenger explosion in 1986. In 1994 the nation watched, rapt, in real time while police chased NFL legend O.J. Simpson in a white Ford Bronco — the closest one could get back then to the immediacy of today’s social media.

TV also has helped viewers make sense of the news as it happens, as an emotional Walter Cronkite did in 1963 when he announced the assassination of President John F. Kennedy. Even now, with the world at our fingertips, people still turned anxious eyes to their television sets on January 6th, 2021, as protests at the US Capitol turned into an insurrection.

These were the historic moments on the Television Academy’s list:

1. The moon landing, 1969

2. 9/11 coverage, 2001

3. John F. Kennedy’s death announced by Walter Cronkite, 1963

4. Martin Luther King, Jr.’s “I Have a Dream” speech

5. CNN’s coverage of Space Shuttle Challenger explosion, 1986

6. O.J. Simpson Bronco car chase, 1994

7. First Kennedy-Nixon presidential debate, 1960

8. Footage of George Floyd’s murder, 2020

9. January 6 insurrection, 2021

10. President-elect Barack Obama’s Election Night speech, 2008

11. Footage of Rodney King’s beating at the hands of police, 1991

12. O.J. Simpson trial verdict airs, 1995

13. Princess Diana’s funeral, 1997

14. Queen Elizabeth II’s coronation, 1953

15. Los Angeles riots in wake of Rodney King verdict, 1992

Groundbreaking ideas

TV programs have also served to challenge audiences and interrogate social norms. In 1969, beloved children’s TV host Mister Rogers invited his neighbor Officer Clemmons, a Black police officer, to cool his feet in a pool on a hot day — a simple but quietly revolutionary act during a time when many pools across the country still banned Black Americans from swimming.

“Star Trek’s” passionate 1968 smooch between William Shatner’s Captain Kirk and Nichelle Nichols’ Uhura wasn’t just a huge moment for Trekkies. It was also one of the first interracial kisses on TV, and caused such a response that Nichols said she received more fan mail for the episode — most of it positive — than for any other during her stint on the show.

What happens on TV happens in the real world, too. The same month Ellen DeGeneres’ character on her eponymous ‘90s sitcom came out as gay, the comedian came out on a Time magazine cover. DeGeneres’s admission was praised by LGBTQ rights groups, but her show was canceled a year later after ratings declined and network executives asked her not to include “gay content” in every episode. She returned to TV in 2003 to host her own daytime talk show, which ended in 2022.

And media was flipped on its head when MTV debuted in 1981 with the Buggles’ “Video Killed the Radio Star,” kicking off its decades-long reign as the TV destination for young pop culture enthusiasts.

Here are the top moments that changed our culture:

1. Mister Rogers dips feet in a pool with Officer Clemmons, 1969

2. MTV premieres with its first music video – “Video Killed the Radio Star,” 1981

3. “Ellen” comes out, 1997

9. “Star Trek” – Kirk and Uhura kiss, 1968

Must-see premieres

These are the series that changed the landscape of television upon their debuts – and occasionally helped change minds.

“Roots,” recently named one of the 10 greatest TV series of all time by Variety, was a landmark series for its unflinching depiction of slavery, racism and Black life in the US from the 19th century to its 1970s present. It aired over eight nights in 1977, signaling to viewers that “Roots” was a must-see event. Matt Zoller Seitz wrote for Vulture that “Roots” amounted to “the first prolonged instance of not merely being asked to identify with cultural experiences that were alien to (White viewers), but to actually feel them.”

When “Sesame Street” debuted in 1969, it was one of the first TV series that aimed to educate and entertain child viewers from all backgrounds — and also happened to star a diverse cast of humans and Muppets. The stalwart series is still airing today, along with “Saturday Night Live” and “The Simpsons” — two other long-running programs that have influenced the current structures of comedy, sitcoms and American TV.

1. “Roots” premieres, introducing viewers to Kunta Kinte (Levar Burton), 1977

Iconic goodbyes

When a beloved series signs off, it’s a huge television event. Before the streaming era, series finales were sometimes bigger than the Super Bowl, drawing millions of viewers eager to see how a series concludes.

The frequently silly “M*ASH” struck a bittersweet chord in its finale, reminding audiences of the mental toll of war, even during peacetime. It’s still the most-watched series finale of all time, with over 106 million viewers glued to their screens to witness Hawkeye bid his comrades goodbye.

One of the most acclaimed series of all time also had one of the most controversial endings. The tense final minutes of the 2007 series finale of “The Sopranos” ended with an abrupt cut to black so unexpected some viewers feared their cable service had cut out. Seventeen years later, fans are still dissecting and debating what happened to the Sopranos family in those last crucial moments.

Talked-about drama

There’s a reason “Who shot J.R.?” is still in the pop culture parlance. People remember where they were when they succumbed to Beatlemania on “The Ed Sullivan Show,” or when a shocking shooting went down on “Dallas,” or when they were subjected to the heartbreaking horror of the Red Wedding on “Game of Thrones.” These are the the TV beats you just couldn’t miss, lest you be left out of the conversation the next day.

Nowadays, those water cooler conversations are mostly happening online as the show airs. But these classic TV moments that stirred audiences when they first aired are still resonant and frequently referenced in contemporary culture.

For all she has done in her career, one of Oprah’s most immortal moments will always be a 2004 surprise giveaway on her show, which peaked with her bellowing, “You get a car! And you get a car!” to members of her screaming audience.

Although we may watch in the privacy of our own homes, these revelatory moments show TV’s power as a meeting place of sorts, where conversations begin and connections are made.
