A radio basically works the same way, except instead of sound vibrations, it is tuned to pick up electromagnetic vibrations. It is tuned to a particular frequency, and picks up the signals with that frequency, just like how the glass picks up the signal from a specific frequency of sound in the air.
Basic principle behind every radio is the process of modulation (superimposition of signals on carrier waves collectively called baseband signal) and demodulation of radio waves.
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.

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
Shortwave radio is used for broadcasting of voice and music to shortwave listeners, and long-distance communication to ships and aircraft, or to remote areas out of reach of wired communication or other radio services. Additionally, it is used for two-way international communication by amateur radio enthusiasts for hobby, educational and emergency purposes.

I was invented in 1896 to 1922.

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.

Radio waves bounce off of the ionosphere and return back to Earth.
