How has the radio survived all these years? On the face of it, there is absolutely no reason why radio should continue to remain popular as entertainment now comes in the form of things such as www.direct.tv and the like. There was a time when typewriter was considered the most formal source of communication. A handwritten letter was a personal and casual thing while a typewritten letter was formality and decorum personified. Who bothers with a typewriter today now that computers are available?

The end product document from a computer is far superior to the typewriter. The computer incorporates all features of the typewriter and offers many other additional features of its own. This is the reason why typewriters have been relegated to antique status and are considered suitable only for museums.

There are some who still prefer the typewriter but there is general acknowledgement that the electronic device has destroyed the utility of the original mechanical device. Television and computers; internet and other such innovations included, ought to have done the same thing for the radio. However, there is a significant advantage that radio offers over all other mediums.

It offers the widest reach possible. We all know how much a radio costs? It is something that can be bought by even the poorest man on the street. A person belonging to the lower middle class or lower class category of society can afford a radio. Governments find it very useful to communicate with large number of persons at a very affordable cost.

There still are places where television is used only as a source of community entertainment and radios are used for personal entertainment. This is not just restricted to developing countries alone.

Regions with harsh landscape and difficult terrain often make use of radios to keep in contact. Even today, a disaster hit region communicates through the radio. This is the reason why the radio continues to remain indispensable.
