Meet the Woman Behind Princess Penelope: Angela Santomero's Mission to Change How Kids Learn

If you've ever watched your child shout an answer at the TV screen - genuinely convinced the character can hear them - there's a good chance Angela Santomero is responsible.

She's the Peabody and two-time Emmy Award-winning creator behind Blue's Clues, Daniel Tiger's Neighborhood, Super Why!, and now Princess Penelope's Purse of Preposterous Things.

Over the course of 30 years, her shows have reached billions of children across more than 120 countries. Malcolm Gladwell called Blue's Clues "one of the stickiest TV shows ever made." Joanne Rogers - Fred Rogers' wife - described Santomero as "a modern-day Fred Rogers."

But Princess Penelope is different from everything that came before it.

And understanding why requires understanding the woman who made it.

From Columbia University to Blue's Clues Angela Santomero didn't stumble into children's media. She pursued it with intention, earning a Master's degree in Child Developmental Psychology from Columbia University's Teachers College with a specific goal: to use media as a tool for teaching children how to think.

Her Master's thesis became the foundation for Super Why!, the PBS literacy series that helped millions of preschoolers learn to read. Her work on Blue's Clues - which she co-created in 1996 - became one of the most studied children's television programs in history, with independent research confirming that viewers significantly outperformed non-viewers on standardized measures of cognitive ability.

The secret wasn't the blue dog. It was the pause.

Santomero pioneered what she calls the pause-and-play method - a deliberate, held moment in every episode where the show stops, asks the child a question, and genuinely waits for the answer before moving on.

That four-beat pause, which seems so simple, is the mechanism through which children shift from passive viewers to active thinkers. It was revolutionary in 1996. It remains the gold standard for interactive children's media today.

A Decade of Building Other People's Brands

After Blue's Clues, Santomero went on to create Daniel Tiger's Neighborhood for PBS - the beloved spin-off of Mister Rogers' Neighborhood that has become one of the most trusted resources for parents navigating preschool emotions.

She created Creative Galaxy and Wishenpoof! for Amazon Studios.

She served as Chief Creative Officer of 9 Story Media Group.

She wrote three books for adults - Preschool Clues, Radical Kindness, and Life Clues- and the children's books she wrote for Blue's Clues and Daniel Tiger sold over 10 million copies worldwide.

Every one of those projects was built on her research-backed curriculum.

Every one of them changed the landscape of children's media.

And none of them were 100% hers.

"I've created brands for everybody else," Santomero said in a 2024 video. "Billions of dollars in brands and marketing and all of these things that I don't get to have decisions over. What I'd really love to do is create a new show that is based on all of the curriculum I'm known for - interactive, socio-emotional, cognitive thinking skills - and create characters and an immersive world."

That show is Princess Penelope's Purse of Preposterous Things.

Why Princess Penelope Is Her Most Personal Work

Princess Penelope is the first children's brand Santomero has created entirely for herself - built from the ground up on her own terms, with her own creative vision, and her own face on camera.

That last part matters.

In every episode of Princess Penelope, Santomero appears as the live-action narrator, bridging the viewer's world with the animated world of Storybook Meadow.

She looks directly at the camera.

She talks to children as if they're right there with her - because in her method, they are.

She introduces Penelope. She opens the purse.

She asks the question.

It's the same warmth and directness that made Blue's Clues feel like a friend, and Daniel Tiger feel like a neighbor. But now it comes with something new: the face of the person who built the whole thing, inviting your child in personally.

The result drew over 4 million views in its first month on YouTube Kids.

The series is now expanding into a book franchise with two debut titles - Princess Penelope's Purse of Preposterous Things and Dragon's Marshmallow Mess - launching April 21, 2026, with further broadcast and streaming distribution in development.

What Parents Should Know

Princess Penelope is designed for children ages 2-5, the same developmental window Santomero has focused on throughout her career.

Every episode uses her proven framework: a clear problem, three unexpected objects from Penelope's magical purple purse, and a direct invitation for your child to help solve it.

The curriculum covers critical thinking, emotional regulation, cooperative thinking, and kindness - the same foundations that made Blue's Clues and Daniel Tiger trusted by parents and educators for decades.

The difference is that this time, the show is built on a digital-first model, streaming on YouTube Kids with new episodes every week. That means your child can access it anywhere, anytime - and the interactive experience is designed to work just as well on a tablet as on a television.

For parents who grew up with Blue's Clues or Daniel Tiger, Princess Penelope is the next chapter of the same story - written by the same person, with the same research-backed heart, and the same unshakeable belief that preschoolers are capable of more than we give them credit for.
