It comes from the war of currents during which Edison was promoting DC (direct current) and Tesla AC (alternate current) for the transmission of the electric energy. AC finally wons due thanks to the use of transformers, which works only in AC. Transformers allows to change voltage and therefore to transmit electric energy on greater distances with more efficiency. Moreover AC generators are quite simpler than DC ones.
