The next important event was in 1910 when Congress passed the Wireless Ship Act. This seems to be the point where the shorter term "radio" began to be used.
Passed in 1910, requiring all ships of the United States traveling over two-hundred miles off the coast and carrying over 60 passengers to be equipped with wireless radio equipment with a range of one-hundred miles. The legislation was prompted by a shipping accident in 1909, where a single wireless operator saved the lives of 1,200 people.
