Bonjour Sesame was the first French translation of Sesame Street, debuting on French national television on September 16, 1974.
The show occupied fifteen minutes of a block shared with the five minute segments L'Île aux Enfants, which featured the full-bodied puppet dinosaur Casimir (Yves Brunier). The Bonjour Sesame portion consisted entirely of dubbed segments from the American show and was composed of about 65% puppet sequences, 25% animated cartoons, and 10% live action sequences.
The French names given to Muppet characters included Bart (Bert), Ernest (Ernie), Macaron (Cookie Monster), Hyacinthe (Herry Monster) and Martoff (The Amazing Mumford).
Bonjour Sesame was replaced in 1978 with a French co-production, 1, Rue Sésame, while L'Île aux Enfants became its own twenty minute series in 1976. 1, Rue Sésame and L'Île aux Enfants would alternate in a slot for the 1981-1982 season.
