Launch of Sesame Street

Sesame Street began with a 1966 dinner party conversation about using TV to educate preschoolers. Creators raised $8 million to launch the show in 1969, but its path wasn't smooth. Test episodes revealed Big Bird was nearly cut entirely, and Mississippi banned the show for its diverse cast before public pressure reversed the decision within 22 days. There's a lot more to this beloved show's origin story than you'd expect.

Key Takeaways

• Sesame Street's concept originated at a 1966 dinner party after Lloyd Morrisett observed his daughter captivated by television test patterns.
• $8 million was raised between 1966–1968 from philanthropic and federal sources, enabling the show's premiere in 1969.
• Five test episodes aired in Philadelphia in July 1969, revealing children preferred Muppet segments over human-only street scenes.
• Mississippi banned Sesame Street on April 17, 1970, citing its integration and diversity messaging, but reversed the ban within 22 days.
• By 1979, just a decade after launch, 9 million children under age 6 were watching Sesame Street daily.

The Dinner Party Idea That Created Sesame Street

Few television programs can trace their origins to a single dinner party, but Sesame Street can. In early 1966, Joan Ganz Cooney hosted a gathering at her New York apartment where Lloyd Morrisett, a Carnegie Corporation vice president, mentioned his young daughter's fascination with television test patterns. That observation sparked a defining question: could television teach preschoolers?

The group recognized television's addictive qualities and debated how to harness them for education, giving birth to an innovative television concept that would reshape children's media. Morrisett's background in experimental psychology and philanthropy helped shape the show's pioneering educational philosophy, ensuring it reached disadvantaged children across all ethnic and socioeconomic backgrounds. Within days, Morrisett hired Cooney to research childhood development and media, formally setting Sesame Street's creation in motion. Cooney's research culminated in a detailed study outlining how television could help prepare young children for school, titled "The Potential Uses of Television for Preschool Education." The report was commissioned by the Carnegie Corporation of New York and ultimately persuaded them to fund the project.

The Research That Proved TV Could Teach Kids

When Joan Ganz Cooney and Lloyd Morrisett set Sesame Street in motion, they needed proof that television could actually teach children — and the research that followed delivered it in remarkable fashion.

The Educational Testing Service confirmed that preschool viewers entered school better prepared in literacy and math than nonviewers. A meta-analysis spanning 24 studies and over 10,000 children across 15 countries revealed an average 11.6 percentile difference in learning outcomes.

Beyond academics, researchers documented strong socio-emotional outcomes, including improvements in compassion, emotional regulation, and social reasoning. Sesame Street proved more scalable than traditional early childhood interventions, reaching millions daily through a single hour of television. You're looking at the largest educational experiment ever undertaken — and it worked. For children from low-income homes, the impact was especially profound, with the show considered equivalent to a full year of preschool.

The meta-analysis was commissioned by Sesame Workshop and presented at the 2013 Biennial Meeting of the Society for Research in Child Development before being published in the Journal of Applied Developmental Psychology.

Why Producers Almost Named It 123 Avenue B?

Before "Sesame Street" became a cultural institution, it nearly launched under a very different name: "123 Avenue B." Joan Ganz Cooney originally conceived the title as a direct nod to Alphabet City, the real Manhattan neighborhood spanning the Lower East Side and East Village, where avenues are labeled with letters rather than numbers.

The realism of the setting appealed to Cooney, but producers ultimately rejected it for key reasons:

• It tied the show too literally to a real address
• It lacked nationwide appeal beyond New York City
• It missed the magical, imaginative quality children needed

"Sesame Street" referenced Arabian Nights evoking wonder and growth. The new name carried memorable alliteration and poetic resonance. The lasting impact of the name change shaped a 50-year global legacy. Art director Victor DiNapoli later clarified that the show's fictional neighborhood was ultimately designed to represent the Upper West Side of New York City. The fictional street is anchored by 123 Sesame Street, a brownstone-type row house that houses multiple families across its apartments.

The $8 Million That Turned the Concept Into a Show

Raising $8 million between 1966 and 1968, Joan Ganz Cooney and Lloyd Morrisett transformed Sesame Street from an ambitious concept into an operational television series. You'd find the funding split evenly between philanthropic support from major foundations like Ford and Carnegie, and a federal funding role through the U.S. Office of Education.

Together, they established the Children's Television Workshop, with Cooney serving as its first executive director. The budget covered the first six months of production, enabling the show's 1969 premiere on NET, PBS's predecessor.

That initial investment proved far-reaching, launching licensing and merchandising revenue streams, supporting international co-productions that generated $96 million by 2005, and sustaining production well beyond those original grants through CTW's strategic control of its own content. The organization later rebranded as Sesame Workshop in 2000, reflecting its expanded mission beyond a single television program. By 1979, 9 million children under age six were watching Sesame Street on a daily basis, demonstrating the show's extraordinary reach among its target audience.

The Sesame Street Test Episodes Nobody Ever Saw on TV

Before Sesame Street reached living rooms nationwide, it had to prove itself in a far more modest setting. In July 1969, five test episodes aired on Philadelphia's WHUY Channel 33, purely for research purposes. Pilot episode feedback and production development challenges shaped everything that follows.

Key takeaways from the testing process:

• Children preferred Muppet segments over human-only street scenes
• Street scenes originally excluded Big Bird and Oscar the Grouch entirely
• Garrett Saunders played Gordon, never appearing in the final series
• Pilot feedback directly triggered Big Bird's creation that summer
• Only Test Show 1 remains fully available today

Those results forced creators to integrate Muppets directly into street segments, fundamentally transforming the show's format before its November 10 premiere. During the July 1969 pilot tapings, key creative figures including Jim Henson, Frank Oz, Jon Stone, and Dave Connell were all present on set together. Joan Ganz Cooney also intervened during this period, insisting that Gordon and Susan be rewritten as a married couple to better reflect the "mommy and daddy" dynamic familiar to the show's young target audience.

How Critics and Parents Reacted to the First Episode

When Sesame Street premiered on November 10, 1969, critics and parents didn't hold back their opinions. The New York Times praised its educational value and innovative format, while parents reported their kids instantly engaged with counting segments and letter introductions. Casting decisions drew attention too, especially the multicultural cast and Kermit the Frog's surprising crossover appearance.

Not everything landed perfectly, though. Production challenges were visible in Big Bird's costume, where exposed head mechanics and an awkward voice drew criticism. Some adult viewers found the rapid scene cuts disjointed, and early Cookie Monster felt less defined than he'd later become.

Still, the warmth of the neighborhood setting and puppet characters like Ernie resonated with families, setting a strong foundation for what Sesame Street would become.

Why Mississippi Banned Sesame Street: And What Came Next

While most of America embraced Sesame Street's debut, not everyone welcomed its vision of integration and diversity. On April 17, 1970, Mississippi's all-white Educational Television Commission voted 3-2 to ban the show.

The consequences of the Sesame Street ban were immediate and fierce:

• Jackson residents protested outside Mississippi Public Broadcasting headquarters
• WDAM-TV in Hattiesburg offered to air the show independently
• Joan Ganz Cooney called it a tragedy for both Black and white children
• The Delta Democrat-Times demanded Mississippi embrace this educational tool
• A pro-Sesame commissioner leaked the real racial motivations to the New York Times

The public pressure that led to reversal of the ban proved overwhelming. Within 22 days, the commission agreed to reinstate the show, though they never formally apologized. Ironically, Mississippi had only just established WMAA Channel 29 in 1970, allocating $390,000 to finally bring educational television to the state. The show had made its broadcast debut on November 10, 1969, just months before Mississippi's controversial decision to remove it from the air.
