1910s
- Early recording media formats: cylinder records versus disk records. In 1877 Thomas Edison invented sound recording technology using a tin cylinder record, and soon thereafter mass-marketed the wax "Edison cylinder". In 1886 Emile Berliner invented disk records. By the late 1890s cylinders and disks were widespread. Cylinders were more expensive to manufacture, but most cylinder players could make recordings. Disks saved space and were cheaper, but due to the constant angular velocity (CAV) of their rotation, the sound quality varied noticeably from the long outer edge to the short inner portion nearest the center; and disk record players could not make recordings. Edison refused to produce the disks until Berliner's patent expired in the late 1910s.
