Mirrored balls were around long before they were called disco balls. A mirrored ball appeared in the 1927 German silent film Berlin: Die Sinfonie der Großstadt, and there’s even a record of one that hung in a Wisconsin hospital in 1912.
By the 1970s, Kentucky’s Omega National Products produced nearly 90% of the disco balls made in the United States. Yolanda Baker began working at Omega in the late 1960s, in the factory’s wood division. She transitioned to the mirror division in 1970 when the disco ball market started taking off. After a few years, she was leading a team of nearly 30 women, producing thousands of disco balls a month. During the peak of disco’s heyday, her team produced about 25 disco balls daily.
