Can you tell us how to get to Sesame Street? This year marks the 50th anniversary of America’s favorite children show, featuring adorable monsters, funny grouches, and a wonderful human cast! To celebrate, we’ve created a list of 50 Sesame Street characters, like Bert, Ernie, the Count, and Oscar the Grouch, including when they all made their debut. While favorites like Big Bird have been on the show since the very first episode in 1969, others, like Elmo, weren’t introduced until years later. Newer favorites, like Julia, the show’s first Muppet on the autism spectrum, are recent additions beloved by a new generation of fans. Whether you’re nostalgic for specific characters like the Sesame Street aliens, the Martians (also known as the “Yip-Yips”), or you want to know about the adorable furry creatures kids are watching today, like Abby Cadabby, our list of Sesame Street Muppets will help you congratulate America’s favorite children’s television show on its 50th year as an educational tool that has helped millions of children for four generations.
