Young Spectator's Theatre (âõðÃÂàîýþóþ ÃÂÃÂøÃÂõûÃÂ, âîÃÂ) was a standard name of a professional theatre for children and youth in many cities of the Soviet Union, usually referred to by this abbreviation: ÃÂÃÂ÷, TYuZ (sometimes translated as "TUZ theatre").
The oldest children's theatre under such a name was Moscow TYuZ (ÃÂþÃÂúþòÃÂúøù ÃÂõðÃÂàÃÂýþóþ ÷ÃÂøÃÂõûÃÂ) (created in 1918, but was short-lived; reestablished in 1921 as "ÃÂþÃÂúþòÃÂúøù ÃÂõðÃÂàôûàôõÃÂõù"; now ) and Bryantsev Youth Theatre in Saint Petersburg, opened in 1922.
A TYuZ was typically a stationary theatre, with a dedicated building that housed several scenes, including a puppet theatre.
While considered by many actors to be less prestigious than "adult" theatres, such theatres served well as entertainment for youth not yet sophisticated enough for more mature theatre.
