The first phonograph cylinders are manufactured in 1888, followed by Edison's foundation of the Edison Phonograph Company in the same year.

In 1887, Edison had turned his attention back to improving the phonograph and the phonograph cylinder.

The following year, the Edison company debuts the Perfected Phonograph.

Edison introduces wax cylinders approximately four and a quarter inches (eleven centimeters) long and two and a quarter inches (five point seven centimeters) in external diameter, which becomes the industry standard.

These have a maximum playing time of about three minutes at 120 RPM, but around the turn of the century the standard speed will be increased to 160 RPM to improve clarity and volume, reducing the maximum to about two minutes and fifteen seconds.

Several experimental wax cylinder recordings of music and speech made in 1888 still exist today.
