Sesame Workshop, the maker of the long-running children’s television show “Sesame Street,” has launched an exclusive, standalone video subscription service. For $4 per month or $30 per year, subscribers will have access to hundreds of ad-free episodes, including shorter 30-minute episodes that have never been seen in the U.S. before. The interface with its simple and colorful buttons was designed especially for kids. Children can watch Sesame Go via the Web, tablets or smartphones.

Sesame Go is not the first time that Sesame Workshop has offered the television shows digitally. Clips of “Sesame Street” are available on the PBS website and YouTube while a limited selection of full episodes is available on Hulu, Netflix and Amazon.

Sesame Workshop collaborated with video platform Kaltura to bring more Cookie Monster and friends to video subscribers. Kaltura is the world’s first and only open source video platform.

“We are moving away from ad-based monetization,” Kaltura founder and President Michal Tsur told GigaOM. She believes that more specialization and subscriptions will continue to grow in online video offerings.

The Sesame Workshop has certainly found its niche teaching literacy, numeracy, emotional well-being, health and respect to young children in over 150 countries. In its almost 45-year history, the show has won 118 Emmy Awards, and influenced more than 80 million kids, according to its website.
