“Mr. Watson, I want you here”, Alexander Graham Bell knew so well that he has created a revolution when he said these words after testing his telephone experiment. It was the first of its kind and an invention that revolutionized the way we communicate with people separated by geographic distances and barriers. Years after its invention, telephones have penetrated almost every nook and corner of this world and a large proportion of  these connections are landline phones. Once a luxury, telephones aremore of a habit now, indispensible requirement of any 20th century citizen. 

Like all other inventions, Telephone unfolds a fascinating story that lead to its birth. It all started when an inspired Scotsman named Alexander Graham Bell invented telephone in 1876. Thomas Watson had fashioned the device – a crude thing prepared out of a funnel, wooden stand, acid, and cooper wires.  All these simple parts lead to the simple earliest call, belie the complicated past. Bell filed the application only few hours before his competitor Elisha Gray filed the notice to patent a telephone. By using the ideas outlined in the notice of invention by Gray, Bell created an operating telephone 3 weeks later to this.
