Radio broadcasting has its origins in the telegraph, invented by Samuel Morse in 1836. In the late 19th century, scientists like Heinrich Hertz and Nikola Tesla began experimenting with wireless transmission of electromagnetic waves through the air. Guglielmo Marconi is often credited with inventing radio in 1895, transmitting the first radio signal across the English Channel. In the early 20th century, radio was used for ship-to-shore communication and broadcasting Christmas music from stations like 8XK helped launch commercial radio. The Radio Act of 1927 established the Federal Radio Commission to regulate stations and frequencies.
