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
=======
The first broadcasting of a radio transmission consisted of Morse code (or wireless telegraphy) was made from a temporary station set up by Guglielmo Marconi in 1895. This followed on from pioneering work in the field by Alessandro Volta, André-Marie Ampère, Georg Ohm, James Clerk Maxwell and Heinrich Hertz. The broadcasting of music and talk via radio started experimentally around 1905-1906, and commercially around 1920 to 1923. VHF (very high frequency) stations started 30 to 35 years later.
In the early days, radio stations broadcast on the long wave, medium wave and short wave bands, and later on VHF (very high frequency) and UHF (ultra high frequency). However, in the United Kingdom, Hungary, France and some other places, from as early as 1890 there was already a system whereby news, music, live theatre, music hall, fiction readings, religious broadcasts, etc., were available in private homes [and other places] via the conventional telephone line, with subscribers being supplied with a number of special, personalised headsets. In Britain this system was known as Electrophone, and was available as early as 1895 or 1899 [sources vary] and up until 1926. In Hungary, it was called Telefon Hírmondó [1893-1920s], and in France, Théâtrophone [1890-1932]). The Wikipedia Telefon Hírmondó page includes a 1907 program guide which looks remarkably similar to the types of schedules used by many broadcasting stations some 20 or 30 years later.
By the 1950s, virtually every country had a broadcasting system, typically one owned and operated by the government. Alternative modes included commercial radio, as in the United States; or a dual system with both state sponsored and commercial stations, introduced in Australia as early as 1924, with Canada following in 1932. Today, most countries have evolved into a dual system, including the UK. By 1955, practically every family in North America and Western Europe, as well as Japan, had a radio. A dramatic change came in the 1960s with the introduction of small inexpensive portable transistor radio, the greatly expanded ownership and usage. Access became practically universal across the world.
