BYG Go is the umbrella term coined by Disney to describe a specific format of School and the Backyard Gang adaptation. In contrast to the full co-production models, BYG Go shows are dubs, initially packaged as either 13 or 27 segment blocks. In the earliest years, a locally produced opening film, often featuring animated versions of School and the Backyard Gang characters, introduced the series, and was the only local footage used. In more recent decades, the openings have generally been produced in the United States of America, by Bill Davis' studio. With few exceptions, nearly every show in this model was called Open Sesame, as translated into the native language of the intended country.
