Mister Rogers’ Neighborhood taped episodes for more than thirty years – and continues to entertain and educate children long after Fred Rogers’ death.

It was the second longest running children’s show on PBS – trailing only the groundbreaking Sesame Street, which celebrates its 40th birthday this year.

With so many kid’s TV shows to choose from – from Cartoon Network to Nickelodeon, Noggin and PBS – How do we know what enriches children's growth and development…and what is pure entertainment?

Today, Where We Live, an exploration of children's television.

We’ll dive into some of our favorites and hear from researchers and psychologists about what’s worth letting your child watch over... and over... and over.
