Along with the economics of the profession, the character of the drama changed towards the end of the period. Under Elizabeth, the drama was a unified expression as far as social class was concerned: the Court watched the same plays the commoners saw in the public playhouses. With the development of the private theatres, drama became more oriented towards the tastes and values of an upper-class audience. By the later part of the reign of Charles I, few new plays were being written for the public theatres, which sustained themselves on the accumulated works of the previous decades.
