Sesame Street

Sesame Street is an American children's television series with many Muppets (puppet characters) and non-Muppet characters (human characters). There are also many animated characters. The show deals with issues like music, song, alphabet, numbers, and teaching children basics in learning, as well as more serious issues like death, divorce, HIV/AIDS, autism, and foster care. Part of the profits, go to an international project for children's schools.
The show has been on TV since January 1, 1969. Jim Henson made the Muppets and a lot of writers and puppeteers worked together to make the show. The Muppets were used afterwards in a different show called "The Muppet Show". "Sesame Street" has been on TV in 120 countries all over the world. More than 4000 episodes have been made over 50 seasons. One unique feature of the show is that the episode number appears at the start of each episode. 
For most of its history, "Sesame Street" had been shown on PBS. In 2015, new episodes began airing on HBO in January 2016, but those episodes would be shown on PBS nine months later. In 2020, Sesame Street aired on HBO for the last time. After five seasons on HBO Max, the show returns to PBS as its first-run program, for the newer episodes, starting with the 51st season.
