A play is form of literature written by a playwright, usually consisting of dialogue or singing between characters, intended for theatrical performance rather than just reading. Plays are performed at a variety of levels, from London's West End and Broadway in New York – which are the highest level of commercial theatre in the English-speaking world – to regional theatre, to community theatre, as well as university or school productions. There are rare dramatists, notably George Bernard Shaw, who have had little preference as to whether their plays were performed or read.
