Several scholars and critics have made a point that Priestley was influenced by theatre because of its dual nature. This dualism is very important because Priestley considered that theatre was a source of enjoyment for the people as well as it tried to educate them. Social and contemporary issues were highlighted in the theatre. It compelled the audience to think analytically about the prevalent actions going in the society. From 1918 to 1930’s there was a periodical increase of new plays in theatres. It achieved the zenith in 1950’s as new society popularized theatre all across the country. People started to talk about actor and actress as well as the message spread by theatres in the society. After this period a sudden decrease in quality plays was noticed because of management and ownership of theatres. It was concentrated in fewer hands who worked for profit. As a result fewer quality plays were produced. It had a bad impact on authors like Priestley and he felt that theatres were cheating the audiences.
