Prediction of the Existance of Radio Waves
During the 1860s a scottish physicist named James Clerk Maxwell predicted the existence of radio waves. Altough this man may have passedaway young. He was never forgotten in terms of his contribution to the "radio world". -
Radio Waves Could be Broadcasted into Space
A german physicist named Heinrich Rudolph Hertz demonstrated that rapid variations of electric current could be projected into space in the form of radio waves similar to those of light and heat. -
Electric Waves Could be Transmitted Wirelessly
A german physicist named Henrich Hertz was the first to prove that we could transmit and recieve electric waves wirelessly. This would be the base line for the creation of radio as we know it today. -
Radios Began to Appear at Sea on Ships
This reduced the isolation of the ships thus improving both reliability and safety. This gave ships more options then ever. Radio gave way for the use of morse code for communication between other ships. -
Electromagnetic Energy Wirelessly Transmitted
Nikola Tesla wirelessly transmitted electromagnetic energy. Nikola Tesla was an American Serbian Inventor, Physicist,and Engineer whom was widely remembered for many of his multiple contributions to the electric science. -
First Radio Signal Sent
Guglielmo Marconi an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. Regarded as the best at PR for his time. -
First Ship to Request Emergency Assistance
The R.F. Matthews was the first ship to request emergency assistance using radio technology. There was an accident between the R.F. Matthews and The East Goodwin Lightship. -
Invention of the Audion Tube
In 1906, Lee De Forest came up with the idea for the audion tube, a vacuum that amplified signals. -
Music in Radio
Music in Radio, is when the broadcast on air mainly produces content of music. It is considered the force that drives radio technology. -
Reginald Fessenden: Christmas Eve 1906
He transmitted voice and music over the air. He played a song on the violin and read a chapter out of the bible. -
First Radio Transmission from an Airplane
First Radio Transmission from an Airplane. This truly showcased how far we were coming in improvements in technology. -
First Continuous Broadcast
On March 8, 1916, Harold Power with his radio company American Radio and Research Company (AMRAD), broadcasted the first continous broadcast in the world. A huge step in the world of radio. -
Edwin Armstrong Helps Develop Radio Features
Inventor Edwin Howard Armstrong is credited with developing many of the features of radio as it is known today. Armstrong patented three important inventions that made today's radio possible. Regeneration, the superheterodyne circuit and wide-band frequency modulation or FM. Edwin Howard Armstrong was very inspirational. -
First Radio Station
First Radio Station was created in Pennsylvania. It's call letters were 8XK, changed to KDKA. -
Regularly Scheduled Radio Stations
Regular Radio Shows began to have schedules with them by 1921. -
WW2 Closing of Radio Stations
All Radio Stations that were not needed by the government were shut down. This is most likely due to the fear of any sort of betrayal that may have put the US at any sort of disadvantage during war.
