About
Human beings rely largely on language as a means of communication. In fact, it has been said that languages - no matter what they may be - are what makes the human race unique from other creatures on this earth. In the past, culture, technology, and basically the set up of societies did not really pose the need for people to learn a language other than their own. The average person, in his lifetime, was only exposed to people from the same culture and environment as he was. As such, there was really no need to learn how to interact and communicate with the rest of the world.
Advances in technology and awareness of other people have changed that situation to a great extent, however. Today, people from all corners of the world have ways and means to interact and communicate with each other. More than this, the need for this interaction and communication has arisen over the years as well. As such, learning another language is not at all that uncommon for many people today.
With the rising demand for learning a language other than one's mother tongue, language schools have cropped up all over the place as well. Language schools have been in existence in many parts of the world for a very long time now. However, it was only in the recent decades that language schools have increased exposure.
