National Orchestra Service specialized in booking
ballroom dance orchestras known as
territory bands. The company's reputation as the premier booking agent in that genre helped them dominate their industry for almost 20 years. Bands that NOS represented were typically smaller than the
Glenn Miller-type orchestras, usually featuring about 12 pieces, sometimes 15; though ensemble sizes tended to wax and wane with the economy. NOS handled bookings in Wisconsin, Minnesota, North Dakota, South Dakota, Montana, Wyoming, Nebraska, Missouri, Kansas, Oklahoma, and military bases. == History ==
