Sesame English is a television/video series developed as a collaboration between Sesame Workshop and Berlitz International. Launched in 1999, with Taiwan and China as the debut markets, the series differs from the typical international versions of Sesame Street in that it was devised as a supplement to ESL instruction. The target age group is children from 4 to 7 years old. Italy began airing the show in 2004, and Polish/Hungary/Croatia as part of Sesame Nook since 2006.
