  • A group of theaters regularly visited in turn by touring companies.Such circuits grew up in the early 18th century when most provincialtowns could not support a permanent theater. Each company developedits own circuit of towns easily reached from their home base. Thecircuits were known by the names of their counties or major cities,such as Aberdeen, Manchester, Newcastle, and Suffolk.

    The circuit system served as a training ground for actorsand developed many outstanding provincial managers. Tate Wilkinson(1739 - 1803) managed a company for 30 years on the York circuit(which included Hull and Leeds); his autobiography was titled TheWandering Patentee (1795). The company run by Sarah Bakervirtually made the Kent circuit its own in the late 18th century,to the extent that Baker built a theater at each of the 10 stops ofher troupe.

    vaudeville circuits developed in America in the late19th century, taking the names of the conglomerates that had theatermonopolies; these included the Orpheum circuit from Chicago to Californiaand the Keith-Albee circuit in the eastern and midwestern states.
