Elmo and Cookie Monster are taking on Netflix. The Sesame Workshop has just launched its own streaming service that lets you stream as many Sesame Street episodes as you want for a monthly fee. Called Sesame Go, the service is browser-based, and includes access to “hundreds” of new and classic episodes of the show, as well as the animated series Pinky Dinky Doo. It’ll cost you $3.99 per month or $29.99 a year. At launch the service is only available in the US, and works on Mac, Windows, and mobile devices.
