A nonprofessional theatre is, simply, one comprised of people who do not derive their income from it and do not spend most of their time engaged in it. There are two distinct categories: (1) nonprofessional groups that present plays with some regularity; and (2) nonprofessional groups that are organized on a one-time basis to present a play or a show for some special purpose. The former represents what is known as community theatre, and the latter falls under the heading of amateur theatre (though both types are amateur, or nonprofessional).
