In 1920, farmer Philo T. Farnsworth gazed at the parallel lines he’d plowed in his beet field and had an inspired thought: electrons could be lined up on a tube and transmit images. His “Image Dissector” invention helped create the TV industry, and we’ve been glued to the tube ever since America’s top radio star, President Franklin D. Roosevelt, made his — and the industry’s — telecast debut in 1939. But we tend to forget most of the countless shows we’ve watched — hey, it’s tough even to keep track of what’s on TV this week (unless you read AARP's weekly What to Watch column and our monthly updates on Netflix and Prime Video). To refresh your memory, here are the events, shows and scenes that truly made history — the 75 TV moments most worth remembering.
April 30, 1939
In the first TV telecast, FDR opens the New York World’s Fair.
January 25, 1949
At the first Emmy Awards, Pantomime Quiz Time wins the most popular television program award. The award was originally supposed to be called the "Ike," short for the iconoscope tube that made TV possible (originally invented to guide flying bombs in World War II). But President Eisenhower was called Ike, and the device used in TVs was called the camera image orthicon tube, so they changed it to the "Immy," then feminized it to the "Emmy."

Vice Presidential nominee Richard Nixon delivers his emotional “Checkers speech," saying he plans to keep the cocker spaniel named Checkers that a citizen gave his 6-year-old daughter, Tricia, and saves his career from a political donations scandal.
June 2, 1953

March 30, 1971
In the proud tradition of Leave It to Beaver, which depicted the first toilet on TV in 1957 in an episode where the kids hide a pet alligator in the toilet tank, All in the Family features TV’s first toilet heard flushing.
April 2, 1974
A streaker races past David Niven, who’s about to present the Oscar for Best Picture. Niven quips, “But isn’t it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings?”
October 25, 1975
Mary finds it impossible not to burst out laughing at the funeral of a famous clown in the legendary Mary Tyler Moore Show episode “Chuckles Bites the Dust.” The New York Times calls it “the funniest half-hour in television history.”

In The Carol Burnett Show’s most famous episode, “Went With the Wind,” she channels Scarlett O’Hara and wears an actual curtain for a dress, explaining, “I saw it in the window and I just couldn’t resist it.” The laugh is the longest in the show’s history and has to be edited down to fit on TV.

September 20, 1977
Fonzie (Henry Winkler) jumps the shark on water skis on Happy Days. In 1985, college student Jon Hein coins the phrase “jumping the shark” to signify the point where a show is doomed. It catches on big time; in 2006 Hein sells his company, Jump The Shark, Inc., for over $1 million. Later, on Arrested Development, Henry Winkler jumps over a tiny shark on a dock.
