 By the early 20th century, radio transmission had become the most efficient way to facilitate communication about commerce and therefore, radio frequencies on the electromagnetic spectrum could constitutionally be regulated.The Wireless Ship Act of 1910 called for Congress to modestly regulate the wireless industry and the Radio Act of 1912 was their first attempt to make more legislative oversight to the entire radio industry.This Act required anyone who wanted to transmit over the radio to have government issued permission in form of a license.
