Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Since the late 1920s, the Soviet Union, through its GRU, OGPU and NKVD intelligence services, used Russian and foreign-born nationals as well as Communist, and people of American origin to perform espionage activities in the United States.  These various espionage networks had contact with various U.S. government agencies, transmitting  to Moscow information that would have been deemed confidential.
