It all started with a big, controversial bet that young kids could actually learn from television. In its inaugural seasons, episodes dedicated to the letter n or the number 5 reflected the zeal of its educational mission and its laser-like focus on pedagogy. But from the moment it was first conceived in a 1967 report presented by its founder, Joan Ganz Cooney, Sesame Street quietly harbored larger ambitions.Born at the tail end of the 1960s, Sesame Street evoked a world that was grounded in a radical, even utopian, vision. The show was big-city urban, gritty, unafraid of controversy, sometimes psychedelic, and most alarmingly to some of its earliest viewers, racially integrated—and proud of it. The original target audience, reported The New York Times, was a “4-year-old, inner-city, black youngster,” and in between its charming, mainstream skits on literacy and numeracy, Sesame Street felt by turns avant-garde, iconoclastic, and revolutionary. Now in its 50th year, Sesame Street has remained astonishingly, resolutely inclusive. Long before the issues were addressed candidly on adult TV, Sesame Street was tackling racism, home eviction, neurodiversity, and disability with its audience of toddlers.
