SAN FRANCISCO (KRON) — There’s a new family on Sesame Street, and it’s a unique one for the children’s show.

Two gay dads, Frank and Dave, and their daughter, Mia, were introduced during the Family Day episode, which you can catch on YouTube or HBO Max. One of the dads was the brother of the character Nina.

The introduction ended with, “Elmo’s so happy that you’re all here!”

It’s a big moment for the long-running show, which first aired in 1969 and had yet to highlight LGBTQ characters in this way.

Sesame Street producers have had to fight wide speculation that its popular characters Bert and Ernie are seemingly gay.

In 2018, the show said the best friends “remain puppets and do not have a sexual orientation.”

Castmember Alan Muraoka called Family Day a “milestone” episode, which he also co-directed.

“Sesame Street has always been a welcoming place of diversity and inclusion. So I’m so excited to introduce Nina’s Brother Dave, his husband Frank, and their daughter Mia to our sunny street,” he said in a Facebook post.
