Further improvements of commercial cylinders
Over the years the type of wax used in cylinders was improved and hardened so that cylinders could be played over 100 times. In 1902 Edison Records launched a line of improved hard wax cylinders marketed as "Edison Gold Molded Records".
In 1906 the Indestructible Record Company began mass marketing cylinder records made of celluloid, an early hard plastic, that would not break if dropped and could be played thousands of times without wearing out. This superior technology was purchased by the Columbia Phonograph Company. The Edison company then developed their own type of long lasting cylinder, consisting of a type of plastic called Amberol around a plaster core, these were called Amberol cylinders. Around the same time Edison introduced 4 minute cylinders, having twice the playing time of the old standard cylinder, achieved simply by shrinking the groove size and spacing them twice as close together in the spiral around the cylinder. Most (but not all) Amberol cylinders are of the 4-minute variety. Edison phonographs for playing these improved cylinder records were called Amberolas. See also: Blue Amberol Records.

Cylinder recordings continued to compete with the growing disc record market into the 1910s, when Columbia (which had been making both discs and cylinders) switched exclusively to discs, and Edison started marketing their own disc records. However Edison continued to sell new cylinder records to consumers with cylinder phonograph machines through 1929. The latest of the new cylinders were simply dubs of disc records.
Cylinder phonograph technology continued to be used for dictaphone recordings for office use into the early 1950s when the cylinder dictaphone was supplanted by audio tape.
