Guymon's growth was helped when most of the businesses moved there from the nearby town of Hardesty. One of these was the newspaper, "Hardesty Herald", which owner Richard B. Quinn quickly renamed as the "Guymon Herald". When Oklahoma became a state in 1907, Guymon claimed 839 residents, and was named county seat of the newly created Texas County. By the 1910 U.S. census, the town had 1,342 residents. It also had three banks, three hotels, four doctors, a flour mill, a grain company, and several retail establishments. A second newspaper, the "Guymon Democrat", was in business. Agriculture became the basis of Guymon's economy. The 1920 census recorded 1,507 residents, which grew to 2,181 in 1930. By 1932, the town had two cream stations and five grain elevators.
