Early in the history or electricity, Nikola Tesla devised a system of three-phase AC electricity combining voltage from those phases. He had calculated that 60Hz was the most effective frequency for that combination. With the backing of the Westinghouse Company, Tesla's AC system became the
standard in the United States.
The German company AEG started generating electricity and became a virtual monopoly in Europe. They decided to use 50Hz instead of 60Hz to better fit their metric standards.
Transformer losses, generator inefficiencies, motor inefficiencies, and distribution losses are higher at 50Hz. However once a country has an infrastructure and its inhabitants have their appliances no one is going to change frequencies.

Most of the world uses 50 Hz. India is 50 Hz because it got it's early electricity generating parts from England.

Hi. You have good answers. From space, the emitted radiation from Earth changes from 50 CPS to 60 CPS and back as the Earth rotates. Have to wonder what the folks on Jupiter might think about that!
