I was invented in 1896 to 1922.
Shortwave.

No, not at all. Shortwave listening is a very popular hobby. You can buy ready-made or build-it-yourself shortwave radios. However, as a lifelong shortwave listener, there is, admittedly, less to listen to on shortwave today that formerly.

Good places to start with would be Radio Shack, Amazon, and places like that. Read the reviews on the different types of portable shortwave radios to find the best one.
shortwave radio band
No - they're on entirely different wavelengths. 105.1 is VHF radio, which penetrates through the ionosphere, and creates a line-of-sight limitation. Shortwave receives Medium- and High Frequency transmissions from 1.8 to 30 MHz - well below the range of VHF radio.
Slinky was invented by mechanical engineer Richard James in Philadelphia, Pennsylvania as a toy and of them were sold within 90 minutes. Slinkys were also used in the Vietnam War, as mobile radio antennas, and are still used today by amateur radio operators for shortwave radio antennas.
Ionosphere
Yes, on shortwave or HF radio (they are the same) the super bowl will be broad cast from multiple locations. It can be found at this link http://mt-shortwave.blogspot.com/2008/02/superbowl-xlii-by-shortwave-radio.html
Radio waves bounce off of the ionosphere and return back to Earth.
