The United Kingdom was the first to use this format, which on Disney Channel replaced the already-existing 'Underfives' block on September 29, 1999.
It was produced and created by Andrew Beecham, who later would go on to work for NBCUniversal and run PBS Kids Sprout. Playhouse Disney outside the United States for many years was completely different from its US counterpart, featuring a format set within a live-action 'Playhouse' set that contained the main room, a bedroom, an attic, a bathroom, and a garden.
