Light, like radio, consists of electromagnetic waves. The major difference between the two is that light waves are much shorter than radio waves. The use of electromagnetic waves for long-distance communications was the beginning of an industry known first as wireless and later as radio. This industry was the foundation for electronics, which brought the world so many fascinating technologies.
